Twenty Plus Two

Twenty Plus Two is a 1961 American mystery film directed by Joseph M. Newman and adapted from the suspense novel of the same name by Frank Gruber.^[1]^[1] The story follows private detective Tom Alder, portrayed by David Janssen, as he investigates the brutal murder of Julia Joliet, a secretary for a prominent Hollywood actor's fan club, which leads him to uncover connections to the 22-year-old disappearance of heiress Doris Delaney.^[2]^[1] Produced by Allied Artists Pictures, the black-and-white film runs 102 minutes and features a supporting cast including Jeanne Crain as the missing heiress, Dina Merrill, Agnes Moorehead, Brad Dexter, and William Demarest.^[1] It incorporates elements of film noir with a jazz-inflected score by Gerald Fried, emphasizing Alder's coast-to-coast pursuit involving flashbacks to the Korean War and hidden identities among suspects.^[1] Released in August 1961, the movie received mixed reviews for its straightforward detective procedural style but is noted for Janssen's performance shortly before his starring role in the television series The Fugitive.^[1] The source novel, published earlier that year by E. P. Dutton, centers on the unlicensed investigator Tom Alder specializing in locating missing heirs, blending pulp fiction traditions with Gruber's signature fast-paced plotting.^[3] Gruber, a prolific author known for over 60 novels and contributions to Black Mask magazine, crafted Twenty Plus Two as a standalone tale outside his popular Johnny Fletcher series.^[4] The adaptation stays faithful to the book's core mystery while streamlining the narrative for cinematic tension.^[1]

Background

Source Material

"Twenty Plus Two" is a mystery novel by American author Frank Gruber, first published in 1961 by E.P. Dutton & Co. in New York. The story features protagonist Tom Alder, a Los Angeles-based private investigator who specializes in locating missing heirs and tracing unclaimed fortunes.^[5] The core premise revolves around Alder's investigation into the murder of a Hollywood movie star's fan club secretary, which uncovers clippings linking the victim to the long-unsolved disappearance of heiress Doris Delaney.^[6] Delaney, the 16-year-old daughter of a wealthy New York family, vanished from her boarding school 22 years prior, an event now tied to the contemporary murder and a web of blackmail, hidden identities, and international connections.^[6] Alder's probe spans locations like Chicago and Honolulu, revealing sordid details of Delaney's past, including an implied pregnancy at the time of her disappearance.^[5] Frank Gruber (1904–1969) was a highly prolific pulp fiction writer, best known for his extensive contributions to Black Mask magazine during the 1930s and 1940s, where he penned dozens of short stories in the hardboiled detective genre.^[7] Transitioning to novels, he authored over 60 books across mystery and western genres, often producing up to four titles annually in the 1940s, blending fast-paced action with clever plotting typical of his pulp roots.^[7] "Twenty Plus Two" aligns with this style, delivering a thriller centered on a resourceful detective unraveling a multi-layered conspiracy through deduction and personal stakes.^[8] Compared to the 1961 film adaptation, the novel offers expanded backstories for key characters, including deeper explorations of Alder's status as a WWII veteran and his past romantic entanglements, such as with an ex-fiancée and a Honolulu-based figure, which are condensed or modified in the screenplay—where Korean War flashbacks set in Tokyo provide additional backstory—for brevity.^[5] The book's intricate personal motivations provide richer context for Alder's relentless pursuit, elements streamlined in the movie's more straightforward narrative.^[5]

Development

The development of Twenty Plus Two centered on adapting Frank Gruber's 1961 novel into a screenplay by the author himself, which emphasized the story's Hollywood milieu through a private investigator navigating the city's underbelly of missing heirs and celebrity secrets. Gruber, a prolific mystery writer, tailored the script to amplify film noir sensibilities, including atmospheric tension and moral complexities inherent to the genre, while retaining the core plot of a murdered fan club secretary uncovering clues to a long-lost heiress. This adaptation process allowed for cinematic enhancements, such as integrating Korean War flashbacks unique to the film that provided backstory for protagonist Tom Alder, portraying him as a veteran haunted by his past.^[1]^[9] Allied Artists Pictures served as the primary studio, greenlighting the project under Gruber's production oversight to capitalize on the demand for low-budget mystery thrillers in the early 1960s. Director Joseph M. Newman was chosen for his prior work in suspenseful narratives, notably directing the 1952 Western-mystery The Outcasts of Poker Flat, which demonstrated his ability to blend character-driven drama with intrigue. The studio's involvement ensured a streamlined pre-production, aligning with Allied Artists' focus on efficient B-movie outputs.^[1] Pre-production unfolded rapidly in early 1961, coinciding with the novel's publication that year, as Gruber had conceived the story with film potential in mind from its inception the previous year. Principal photography commenced in January 1961 and wrapped by February, reflecting the swift timeline typical of Allied Artists productions. Key creative decisions included casting David Janssen as Tom Alder to leverage his burgeoning stardom from the television series Richard Diamond, Private Detective (1957–1960), where he had honed a charismatic tough-guy persona suited to the role. These choices positioned the film as a bridge between television and theatrical mystery fare.^[10]

Plot

Synopsis

The film opens with the brutal murder of Julia Joliet, the devoted secretary and fan club president for Hollywood movie star Leroy Dane, whose apartment yields crucial evidence: a collection of yellowed newspaper clippings detailing the disappearance twelve years earlier of wealthy teenage heiress Doris Delaney.^[1] This discovery draws in private investigator Tom Alder, a specialist in locating missing heirs who served in the Korean War, as he is hired by Dane to probe the killing and unravel its ties to the long-cold Delaney case.^[11] Alder, portrayed by David Janssen, methodically pursues leads across Los Angeles and beyond, connecting the murder to Delaney's vanishing in 1949 and uncovering threads involving Dane's inner circle, a war buddy's enigmatic widow named Nicki Kovacs (played by Dina Merrill), and buried family secrets from the heiress's affluent background. His investigation exposes a web of deception, including wartime encounters in Japan and potential inheritance disputes, forcing Alder to confront personal echoes from his military past as suspects multiply.^[12]^[1] The narrative builds to a tense climax where Alder pieces together the true identity of the long-lost heiress and the murderer's desperate motive rooted in a concealed fortune, delivering resolution to the intertwined mysteries while highlighting the investigator's unyielding pursuit of hidden truths.^[11]^[12] The film adapts the source novel but shortens the Delaney disappearance timeline from 22 years to 12.^[13]

Themes

The central theme of Twenty Plus Two revolves around hidden identities, as the investigation into the murder of a Hollywood fan club secretary uncovers connections to a long-lost heiress, Doris Delaney, whose disappearance twelve years earlier suggests she assumed a new life to escape her past. This motif mirrors the concealed personal histories of characters navigating post-war America, where individuals reinvent themselves amid societal upheaval and unresolved secrets. The protagonist, Tom Alder, grapples with his own obscured wartime experiences, illustrating how buried truths shape interpersonal deceptions and drive the narrative's tension.^[13]^[11] The influence of the Korean War permeates the film through flashbacks that depict Alder's physical and emotional trauma, including a battlefield wound and a painful romantic betrayal via a "Dear John" letter, symbolizing broader motifs of lost connections and lingering psychological scars. These sequences underscore unresolved personal histories in a nation transitioning from conflict, where veterans like Alder confront fragmented identities and the difficulty of reintegration. The war's shadow extends to the era's sense of disconnection, amplifying the mystery's exploration of what remains hidden beneath everyday facades.^[14]^[11] A subtle critique of Hollywood glamour emerges in the contrast between the illusory world of celebrity—embodied by the vain movie star Leroy Dane, a supposed war hero whose fan club secretary's murder shatters the veneer—and the stark, investigative reality that exposes underlying deceit and opportunism. Dane's persona highlights the industry's superficial allure, juxtaposed against the film's gritty procedural elements, revealing how fame conceals moral compromises in post-war entertainment culture.^[14]^[13] Motifs of inheritance and loss are woven throughout, evoking the passage of time since Delaney's disappearance and the potential for contested fortunes amid familial grief. Her mother's reclusive persistence in believing Doris alive symbolizes the enduring weight of absence, tying personal loss to broader themes of disrupted legacies and the emotional toll of unresolved mysteries.^[13]^[11]

Cast and Characters

Principal Cast

David Janssen portrays Tom Alder, a laconic private investigator specializing in missing persons cases, whose role draws on Janssen's recent television fame as the lead in the crime series Richard Diamond, Private Detective (1957–1960) and emphasizes the character's moral ambiguity in navigating personal ties and professional ethics.^[1]^[14] Jeanne Crain plays Linda Foster, the protagonist's former romantic interest who becomes a key figure in the unfolding mystery, with Crain's casting leveraging her established image as a 1940s Hollywood starlet from films like Pinky (1949).^[1]^[11] Dina Merrill makes one of her early feature film appearances as Nicki Kovacs / Doris Delaney, a woman connected to the investigator's Korean War past with a mysterious background, highlighting Merrill's poised socialite demeanor derived from her upbringing in a prominent family.^[1]^[14] Brad Dexter stars as Leroy Dane, an arrogant Hollywood movie star and client entangled in the central intrigue, drawing on Dexter's established tough-guy persona from Westerns such as The Magnificent Seven (1960).^[1]^[11] These roles interconnect through the film's investigation of a murder and disappearance, blending personal histories with suspenseful revelations.^[1]

Supporting Roles

Agnes Moorehead plays Mrs. Delaney, the grieving mother of the missing heiress Doris Delaney, whose portrayal infuses the story with emotional depth through her interactions with the lead investigator.^[14] As a veteran actress, Moorehead drew on her acclaimed performance as Charles Foster Kane's mother in Citizen Kane (1941) to deliver a nuanced supporting turn marked by subtle intensity.^[15] Robert Strauss portrays Jimmy Honsinger, a New York detective and colleague to the protagonist who offers comic relief amid the tension of the murder probe.^[16] Strauss, renowned for his humorous role as the boisterous POW Stanislas "Animal" Kucharski in the military comedy Stalag 17 (1953), leverages his background in such ensemble-driven farces to lighten the film's noir atmosphere.^[17] The ensemble extends to secondary figures such as fan club members and war veterans, whose depictions underscore the seedy undercurrents of Hollywood's glamour and deception.^[1] For instance, Brad Dexter's role as a fraudulent war hero exemplifies how these characters contribute to the film's exploration of hidden identities and moral ambiguity within the industry.^[1]

Production

Filming Locations

The principal filming locations for Twenty Plus Two were centered in the Los Angeles area, reflecting the film's setting as a Hollywood mystery. Much of the production occurred at the Allied Artists Studios in Hollywood, California, where interior scenes such as office environments and several exteriors were captured on studio backlots. This studio-based approach allowed for efficient control over production elements, including the use of cover sets to mitigate disruptions from early 1961 rainfall in Southern California.^[18]^[10] Due to the low-budget constraints typical of Allied Artists Pictures, a studio specializing in economical B-movies during the era, the majority of the film was shot within urban Los Angeles confines rather than distant or elaborate sites. Key exterior sequences included shots at Los Angeles International Airport (1 World Way, Los Angeles, California), featuring passengers boarding a United Airlines DC-8, which contributed to the narrative's travel motifs between cities like Los Angeles and New York. These choices emphasized practical, local logistics to keep costs down while maintaining the story's West Coast ambiance.^[19]^[10] Nighttime streets in Los Angeles were selected for several pivotal scenes, enhancing the film's noir-inspired tension through shadowy urban visuals that evoked the genre's characteristic mood of intrigue and isolation. Brief Korean War flashbacks were handled primarily on soundstages at the Allied Artists facility, supplemented by stock footage to depict wartime elements without extensive on-location shooting. Overall, these location decisions by director Joseph M. Newman aligned with the production's modest scale, completed amid winter weather challenges in early 1961.^[11]^[10]^[18]

Technical Aspects

The cinematography for Twenty Plus Two was provided by Carl Guthrie, who filmed the production in black-and-white with a widescreen aspect ratio of 1.66:1, enhancing the film's moody, noir-inspired aesthetic through its emphasis on night scenes and stark interiors. This visual approach, suited to the story's investigative tone, featured flat, rectangular Kennedy-era architecture and nondescript sets that underscored the low-budget constraints while contributing to the overall suspense.^[1] Editing duties fell to George White, who assembled the 102-minute runtime with a focus on dialogue-heavy sequences that drive the plot's mystery elements, though the pacing has been noted as uneven, resembling an extended television episode at times.^[1] This structure prioritized investigative interrogations and revelations, using cuts to build tension without relying on elaborate transitions. The film's sound design employed a mono mix via the Westrex Recording System, centering on clear dialogue to reflect the 1960s vernacular of its characters and settings. Complementing this was the debut film score by composer Gerald Fried, which incorporated jazzy cues evocative of the era to amplify suspense during key thriller moments.^[1] Special effects were kept to a minimum, with the production depending on practical sets and locations to convey realism in murder scenes and flashbacks, aligning with the film's modest budget and emphasis on narrative over spectacle.^[1]

Release and Distribution

Premiere and Marketing

Twenty Plus Two had a wide U.S. release on August 13, 1961, managed by Allied Artists Pictures.^[20]^[1] Allied Artists handled the marketing campaign, promoting the film's mystery elements to appeal to audiences of suspense thrillers.^[1] Distribution was managed by Allied Artists for the U.S. release, often paired on double bills with other B-movies like The George Raft Story.^[21] International rollout was limited, primarily through the studio's subsidiaries in Europe and Asia, where the film was sometimes retitled It Started in Tokyo.^[20]

Box Office Performance

Twenty Plus Two had a modest box office performance, with local grosses ranging from tepid to mild in various U.S. markets during late 1961 (e.g., $3,000 in Minneapolis, $6,000 in Washington, D.C.).^[22] The film played in theaters into November 1961 but was later shown in drive-ins and second-run houses.^[22] Several factors influenced this outcome. The release year of 1961 was highly competitive, with major blockbusters such as West Side Story dominating the box office and drawing audiences away from smaller productions like Twenty Plus Two.^[23] On a positive note, star David Janssen's rising popularity from his television work, particularly Richard Diamond, Private Detective, helped attract some viewers. Internationally, the film earned limited revenue, primarily from dubbed versions distributed in Europe.^[24]

Reception

Critical Reviews

Upon its release in 1961, Twenty Plus Two garnered mixed notices from critics, with praise centered on its lead performance and script efficiency alongside critiques of its conventional structure. Retrospective assessments have echoed these sentiments while emphasizing both strengths and shortcomings in the film's execution. Common praises include the effective buildup of suspense through its intricate missing-heiress storyline and the strong on-screen chemistry between Jeanne Crain and Dina Merrill, which adds emotional depth to the interpersonal dynamics. Director Joseph M. Newman's economical storytelling was frequently lauded for maintaining narrative momentum within the constraints of a low-budget production, drawing on pulp influences to deliver a tidy whodunit resolution.^[25] Criticisms often focused on the predictability of its twists, which some reviewers felt undermined the intrigue, and underdeveloped subplots that failed to explore character backstories adequately. Several commentators viewed the film as derivative of 1940s detective classics like those featuring Philip Marlowe, lacking the innovative edge or moral ambiguity of earlier noir entries, resulting in a sense of familiarity over freshness.^[11] In aggregate, the film holds a 6.2/10 rating on IMDb based on 690 user votes (as of November 2025), reflecting moderate appreciation among general audiences. On Rotten Tomatoes, it has no Tomatometer score due to a limited number of 2 critic reviews (50% fresh if calculated), underscoring its niche appeal within the mystery genre.^[2]^[26]

Audience Response

Upon its 1961 release, Twenty Plus Two garnered positive word-of-mouth among mystery fans, aided by David Janssen's rising star power from his lead role in the television series Richard Diamond, Private Detective (1957–1960), which drew familiar TV viewers to theaters.^[25] The film's noir-inspired detective storyline resonated with audiences appreciative of Janssen's laconic private eye persona, contributing to modest grassroots interest despite its low-budget production.^[27] Home video releases, including VHS tapes in the late 20th century and a 2011 DVD from Warner Archive, further boosted retrospective viewings among dedicated fans.^[28] In modern reevaluations, Twenty Plus Two holds an average rating of 3.2 out of 5 on Letterboxd from 234 users (as of November 2025), who often praise its groovy 1960s atmosphere, crisp visuals, and entertaining mystery elements while critiquing dated pacing and contrived plot devices. On IMDb, it averages 6.2 out of 10 from 690 user ratings (as of November 2025), with reviewers highlighting Janssen's engaging performance and the film's nostalgic TV-like vibe akin to 1950s–early 1960s detective shows, though many note implausibilities in the war subplot tying into the central mystery. Fan discussions in user reviews emphasize the Korean War backstory as a distinctive but uneven feature that adds depth to Janssen's character.^[29]^[2]^[30] The film has primarily appealed to older demographics nostalgic for mid-20th-century detective tropes, evoking the era's private eye templates seen in Janssen's prior TV work, though it connects less with younger viewers who find its stylistic choices and narrative conventions outdated.^[27]^[31]
