With a background in classical and experimental theater, Berkeley transitioned to screen acting after training in New York and moving to Los Angeles, where he first appeared as Christopher Crawford in the 1981 film Mommie Dearest.[1][2] Berkeley gained prominence through supporting roles in major films, including Todd in Terminator 2: Judgment Day (1991), NASA public affairs officer Henry Hurt in Apollo 13 (1995), and Secret Service Agent Gibbs in Air Force One (1997).[3] His television career includes standout performances as the doomed counterterrorism agent George Mason across two seasons of 24 (2001–2002), the serial killer Red John in The Mentalist (2008–2013), the manipulative operative Percy Rose in Nikita (2010–2013), and the opportunistic leader Gregory in The Walking Dead (2016–2018).[1][3] These roles often featured morally ambiguous figures, showcasing his skill in conveying intensity and nuance.[2] In addition to acting, Berkeley is an accomplished painter, sculptor, and makeup artist, having designed his own makeup for 24.[4] He has received accolades such as the Art Carney Award for excellence in theater and a Lifetime Achievement Award from the Garden State Film Festival.[3] Berkeley is married to actress Sarah Clarke, his co-star from 24, since September 2002; the couple has two daughters and resides in Maine.[5] As of 2025, he is transitioning toward directing while continuing to act in projects like the upcoming horror thriller Oddities.[6][3]Early life and education
Upbringing and family
Xander Berkeley, born Alexander Harper Berkeley on December 16, 1955, in Brooklyn, New York City, was raised primarily in New Jersey following his family's relocation from the city.[7] His ancestry is English and Scottish, with a smaller German component traced through genealogical records of his forebears, including paternal lines from New York and maternal roots in Arkansas and Texas.[8][9] Berkeley grew up in a middle-class household that nurtured artistic inclinations, with his father working as a painter and his mother serving as a schoolteacher and skilled seamstress who crafted costumes for him.[7][10] This environment, centered in the greater New York area, encouraged creative pursuits from a young age, though specific details about his parents' names or any siblings remain limited in public records.[7] As a child and adolescent in New Jersey, Berkeley developed an early interest in experimental theater, participating in local improvisational groups such as the Black River Playhouse, where he acted out stories and skits often inspired by books.[10][11] His mother's custom costumes fueled this passion, preferring them over conventional toys and fostering a foundation in performance that shaped his later endeavors.[7]Education and training
Berkeley attended Hampshire College in Amherst, Massachusetts, where he pursued studies in theater and the arts as part of the Five College Consortium, which included institutions such as Smith College, Mount Holyoke College, Amherst College, and the University of Massachusetts. During his time there, he actively participated in theater productions across these campuses, gaining early practical experience in performance and stagecraft.[4][12] Following his graduation, Berkeley honed his skills through extensive work in regional and repertory theaters throughout the United States, including experimental and off-Broadway productions in New York City. This period allowed him to build a strong foundation in classical and contemporary theater techniques, performing in diverse roles that emphasized ensemble work and innovative staging.[1][13] In New York, Berkeley underwent intensive acting training at the HB Studio and directly studied under renowned instructors Uta Hagen and Lee Strasberg, whose methods focused on emotional realism and psychological depth in character development. These sessions, drawing from the Meisner and Method acting traditions, were pivotal in refining his approach to improvisation and truthful performance.[12][14] By the early 1980s, after being spotted by a casting agent during an off-Broadway play, Berkeley relocated to Hollywood to transition into screen acting, marking the end of his formal preparatory phase.[4][13]Career
Early roles
Berkeley began his acting career in 1981 with his film debut as Christopher Crawford in the biographical drama Mommie Dearest, portraying the adult son of Joan Crawford in a supporting role that marked his entry into Hollywood cinema.[15] That same year, he made his television debut with a minor appearance as a Marine in the MAS*H episode "Give 'Em Hell, Hawkeye," followed by a guest spot as Tom in The Incredible Hulk episode "A Minor Problem" in 1982.[16] These early small-screen roles, often uncredited or brief, showcased his ability to handle ensemble dynamics in established series.[3] Throughout the mid-1980s, Berkeley continued to build his resume with supporting parts in both film and television, including the role of Kent Sutcliffe, Tom Hanks' college roommate, in the comedy Volunteers (1985), and Bowery Snax, a quirky punk figure, in Alex Cox's Sid and Nancy (1986).[14] On television, he appeared in guest spots such as on The A-Team (1984) and Miami Vice (1987, as record producer Tommy Lowell in the episode "Like a Hurricane").[17] These roles frequently cast him in eccentric or antagonistic supporting characters across genres, from action to drama, helping him gain visibility in episodic television.[18] By the early 1990s, Berkeley had accumulated dozens of credits, including a notable guest appearance as Dr. Hodge in the The X-Files episode "Ice" (1993), further demonstrating his versatility in science fiction and mystery formats.[19] However, he faced challenges with typecasting, often auditioning for and landing villainous or quirky supporting parts in episodic TV, a pattern that persisted from his intensive early audition process in Los Angeles, where he handled up to three tryouts per day amid personal and professional stresses.[18] This accumulation of minor roles across approximately 30 credits by 1991 established his reputation as a reliable character actor adept at genre work, laying the groundwork for more prominent opportunities.[20]Television work
Berkeley's breakthrough television role came in 2001 as George Mason, the director of the Counter Terrorist Unit (CTU) in the Fox thriller series 24, where he appeared across the first two seasons until his character's sacrificial death in a nuclear threat scenario. Initially cast as a one-episode guest, Berkeley's nuanced portrayal of a flawed authority figure—marked by moral ambiguity, personal sacrifice, and unexpected vulnerability—earned him expanded screen time and widespread acclaim for elevating the show's high-stakes drama, significantly boosting his profile as a versatile character actor. This performance marked a pivotal shift in his career, transitioning him from supporting film parts to prominent serialized television antagonists. Building on this momentum, Berkeley embodied manipulative authority figures in subsequent series. In Nikita (2010–2012), he played Percival "Percy" Rose, the ruthless founding director of the black-ops organization Division, across all 44 episodes of the first two seasons, delivering a chilling depiction of calculated ambition and ideological zeal that drove much of the show's early conflict. His ability to infuse Percy with layers of charisma and menace underscored Berkeley's knack for complex villains, further solidifying his reputation in action-thriller genres. Berkeley's television arc continued with a standout guest arc in The Mentalist (2008–2013), where he portrayed Sheriff Thomas McAllister, unmasked in season 6 as the elusive serial killer Red John, the series' central antagonist responsible for dozens of murders.[21] Appearing in key episodes spanning seasons 1 and 6, Berkeley's subtle buildup of the character's affable facade concealing sociopathic cunning provided a shocking payoff, praised for its psychological depth and impact on the procedural's narrative resolution.[22] From 2016 to 2018, Berkeley took on a series regular role as Gregory, the opportunistic and cowardly leader of the Hilltop community in The Walking Dead during seasons 7 through 9, appearing in 37 episodes and earning promotion to regular status ahead of season 7 for his portrayal of a survivor whose self-preservation instincts clashed with communal ethics.[23] This role highlighted his range in post-apocalyptic ensemble dynamics, contrasting moral ambiguity with outright villainy in prior parts. Other notable contributions include his recurring role as Charles Monroe, a Detroit mobster, in Justified season 5 (2 episodes), where he captured the character's sly criminal demeanor amid Kentucky's underworld. More recently, in 2023, Berkeley made a memorable guest appearance as Captain Gilad Pellaeon in The Mandalorian's season 3 episode "Chapter 23: The Spies," introducing the Imperial officer's strategic poise in the Star Wars universe. Throughout his career, Berkeley evolved from frequent guest spots in the 1980s and 1990s to series regulars in major network and cable shows, amassing over 100 television credits by 2025 and establishing himself as a go-to performer for morally gray leaders whose depth propels ensemble narratives.[20]Film work
Xander Berkeley began his film career in the early 1980s with small roles in independent and studio productions, gradually building a reputation for versatile supporting performances across genres.[20] His breakthrough in major cinema came with James Cameron's Terminator 2: Judgment Day (1991), where he portrayed Todd Voight, John Connor's abusive foster father, a brief but memorable role that highlighted his ability to convey quiet menace in high-stakes action sequences.[24] This appearance marked the start of Berkeley's frequent casting in antagonistic or authoritative figures, often as corrupt officials, agents, or everyday threats in thrillers and dramas. In the horror genre, Berkeley delivered a nuanced supporting turn as Trevor Lyle, the skeptical academic husband to the protagonist in Bernard Rose's Candyman (1992), contributing to the film's exploration of urban legends and racial tensions through his character's intellectual detachment.[25] He continued this pattern in action blockbusters, playing Secret Service Agent Gibbs, a treacherous insider aiding the hijackers, in Wolfgang Petersen's Air Force One (1997), a role that underscored his knack for portraying betrayers within positions of trust. Berkeley's work extended to indie dramas, such as his cameo as the Cynical Cabbie in Mike Figgis's Leaving Las Vegas (1995), where he interacted with Nicolas Cage's self-destructive protagonist, adding layers to the film's raw depiction of addiction and isolation. Berkeley's filmography diversified into ensemble superhero fare with his portrayal of Detective Vic Gigante, a corrupt NYPD officer on a mobster's payroll, in Matthew Vaughn's Kick-Ass (2010), blending dark humor with moral ambiguity in the satirical take on vigilantism. By 2025, he had amassed over 100 film credits, consistently excelling in roles that embodied authority figures turned adversaries—ranging from military personnel and law enforcement to political insiders—across action, horror, and dramatic narratives.[20] Recent projects include his depiction of George Shultz, the influential Secretary of State, in Sean McNamara's biopic Reagan (2024), bringing gravitas to the historical figure's Cold War diplomacy. He also appeared in Julia Verdin's No Address (2025), playing Harris, a homeless veteran grappling with PTSD amid societal neglect, further showcasing his range in socially conscious dramas.Voice acting
Berkeley began incorporating voice acting into his career during the 2000s, leveraging his distinctive gravelly timbre to portray a range of antagonists and complex characters in animated series and video games, extending his reputation as a versatile character actor.[26] In animation, Berkeley voiced the villainous Quentin Beck / Mysterio in the acclaimed series The Spectacular Spider-Man across its 2008–2009 run, bringing a menacing, theatrical flair to the special effects expert turned supervillain who deceives Spider-Man with illusions.[27] He also lent his voice to Dr. Kirk Langstrom, who transforms into the bat-like Man-Bat, in the 2014 DC animated film Son of Batman, emphasizing the scientist's tormented duality in a story centered on Batman's son Damian Wayne.[28] Earlier, in the Cartoon Network series Teen Titans (2003–2006), Berkeley provided voices for multiple foes, including the time-traveling dictator Warp, the authoritarian leader Mento of the Doom Patrol, and the militaristic General Immortus, showcasing his ability to convey authority and menace in ensemble superhero narratives.[29] More recently, he voiced the Imperial officer Captain Gilad Pellaeon in the Star Wars animated anthology Tales of the Empire (2024), contributing to stories exploring moral ambiguity in the galaxy far, far away.[30] Berkeley's video game work highlights his vocal range in interactive media, most notably as the prophetic, fan-favorite antagonist Zachary Hale Comstock in BioShock Infinite (2013), where he delivered a chilling performance as the self-proclaimed prophet ruling the floating city of Columbia, blending zealotry and vulnerability to enhance the game's narrative depth.[26] This role, in particular, garnered praise for amplifying the character's ideological fervor and tragic undertones in one of the decade's most critically acclaimed titles.Awards and nominations
Berkeley's most notable award win came in 2013 when he received the Streamy Award for Best Male Performance in a Drama for his lead role in the web series The Booth at the End (2011–2012), recognizing his nuanced portrayal of a mysterious counselor in a psychological thriller format that pioneered streaming content.[31][32] In television, he earned a nomination for the Screen Actors Guild Award for Outstanding Performance by an Ensemble in a Drama Series in 2003, shared with the cast of 24 for their work in the high-stakes counterterrorism drama, highlighting his contribution as the complex antagonist George Mason.[33] Despite this recognition, Berkeley has not received major Emmy or Golden Globe nominations, often attributed to his frequent casting in supporting roles that amplify ensemble dynamics rather than lead billing.[33] For his contributions to independent and genre films, Berkeley has garnered several honors at film festivals, including the Art Carney Award for excellence in acting and a Lifetime Achievement Award at the Garden State Film Festival, affirming his impact on character-driven cinema outside mainstream blockbusters.[3][34] By 2025, Berkeley's career accolades total approximately 20 wins and 10 nominations across various platforms, with these selections underscoring his acclaim in niche and emerging media. These recognitions have notably boosted his visibility in the streaming era, facilitating transitions to web series and festival circuits that parallel his genre television work.[35]| Year | Award | Category | Project | Result |

Personal life
Marriage and family
Berkeley met actress Sarah Clarke on the set of the television series 24 in 2001, where they portrayed characters Nina Myers and George Mason, respectively.[5] The couple began dating shortly after and married on September 7, 2002, in a private ceremony at a 19th-century church in Millbrook, New York, attended by about 100 guests.[36] Berkeley and Clarke have two daughters: Olwyn Harper, born on September 23, 2006, and Rowan Harper, born in March 2010.[4] The family has maintained a low public profile regarding their children, sharing limited details to protect their privacy.[37] The family resides in Maine.[3] Despite the demands of their acting careers in Hollywood, Berkeley and Clarke have balanced family life by making occasional joint appearances at events, such as the PS Arts Express Yourself 10th Anniversary in 2007 with their infant daughter Olwyn and the 3rd Annual Streamy Awards in 2013.[5][38] They emphasize privacy in family matters, focusing on nurturing their immediate family unit away from the spotlight.[4]Artistic interests
Berkeley has demonstrated proficiency as a make-up artist, drawing from his early training in theater and visual arts, where he honed high-level skills that extended into professional credits. In addition to designing his own character makeup for the role of George Mason on the television series 24, where the character endured physical trauma, he contributed as a make-up artist on the short film The Consultants.[20][39] Further, Berkeley offered his expertise in prop making and artistry for make-up and prop artifacts on the series Salem, showcasing his technical abilities in early film and television work.[40] These skills, rooted in classical and experimental theater education in New York, including private classes in movement and voice from institutions like the Moscow Arts Theater and Royal Academy of Dramatic Art, influenced his transition to on-screen roles while maintaining a hands-on approach to visual creation.[41][42] Beyond make-up, Berkeley is an active painter and sculptor whose works explore personal and abstract themes, often blending organic forms with layered textures. His pieces have been exhibited in galleries, such as the 2019 solo show "X-cavations" at The Dime in Chicago's Wicker Park neighborhood, where paintings and sculptures reflected his multifaceted creative process.[7] Online, his original artworks are showcased and available through xanderoriginal.com, allowing direct access to his evolving portfolio of paintings and carved sculptures.[43] These pursuits stem from early exposures to diverse art forms during his formative years, which shaped his artistic style and provided a counterbalance to the demands of acting by fostering personal expression and creative autonomy.[44][45] Berkeley integrates his art into everyday life and professional environments, creating custom pieces that enhance personal spaces and contribute to film productions. For instance, in 2025, his paintings and carved head sculptures served as set dressing for the film Recluse, directed by Henry Chaisson, merging his hobbies with collaborative storytelling.[46] This practice, influenced by his theater background, offers a grounding outlet amid an acting career spanning over 240 credits, allowing him to channel creativity into tangible, non-performative forms that sustain emotional balance.[41] Recent activities in 2025, including Instagram documentation of his sculpting process—such as painting and sanding techniques shared in September—highlight ongoing experimentation, while he has expressed aspirations for gallery openings to support his artistic endeavors alongside acting.[47][48]Filmography
