James Beaver Jr., joining us for his portrayal of curmudgeonly hunter Bobby Singer, was born in Laramie, Wyoming and grew up in Irving, Texas. Despite appearing in some elementary school plays, he showed no particular interest in an acting career, but immersed himself in film history and expressed a desire for a career as a writer. After serving in the United States Marine Corps in both the US and Vietnam as a radio operator and supply chief, he attended Oklahoma Christian University, where he made his theatrical debut in The Miracle Worker. Transferring to Central State University (now the University of Central Oklahoma), he performed in numerous plays and supported himself as a cabdriver, movie projectionist, tennis-club maintenance man, and an amusement-park stuntman at Frontier City. He also worked as a newscaster and hosted jazz and classical music programs on radio station KCSC. He completed several plays as well as his first book, on actor John Garfield, while still a college student, before graduating with a degree in oral communications in 1975.
Jim made his professional stage debut in 1972 while still a college student in Rain at the Oklahoma Theatre Center, and later performed extensively in local theatre in the Dallas area, supporting himself as a film cleaner at a film rental firm and as a stagehand for the Dallas Ballet. He joined the Shakespeare Festival of Dallas in 1976 and was commissioned in 1979 by the Actors Theatre of Louisville to write the first of three plays for the company – Spades, followed by Sidekick and Semper Fi – and was twice a finalist in the theatre’s national Great American Play Contest, for Once Upon a Single Bound and Verdigris. Along with plays, he continued writing for film journals and for several years was a columnist, critic, and feature writer for the National Board of Review of Motion Pictures’ magazine Films in Review.
Moving to New York City in 1979, Jim worked steadily onstage, simultaneously writing plays and researching a biography of actor George Reeves. He starred roles in such plays as The Hasty Heart, The Rainmaker, and The Lark, and toured the country as Macduff in Macbeth and in The Last Meeting of the Knights of the White Magnolia, also ghostwriting the book Movie Blockbusters for critic Steven Scheuer.
In 1983, he moved to Los Angeles to continue research on his George Reeves biography, working for a year as the film archivist for the Variety Arts Center. He was invited to join the prestigious Theatre West company in Hollywood, where he continues as an actor and playwright to this day. After his play Verdigris was produced to acclaim in 1985, he was signed by the Triad Artists agency and immediately began writing episodes of series including Alfred Hitchcock Presents (his first script for which he received a 1987 CableACE Award nomination), Tour of Duty and Vietnam War Story, also working occasionally in small roles in films and television.
The 1988 Writers Guild of America strike fundamentally altered the freelance television writing market, putting an abrupt halt to Jim’s TV writing career, but his acting career took off after a chance meeting led to the role as the best friend of Bruce Willis in Norman Jewison’s drama about Vietnam veterans, In Country, where Jim was the only actual Vietnam veteran among the principal cast. He’s subsequently appeared in many popular films, including Sister Act, Sliver, Bad Girls, Adaptation, Magnolia and The Life of David Gale, and starred in television series including Thunder Alley as Ed Asner’s comic sidekick, and Reasonable Doubts as homicide cop Earl Gaddis, also playing French Stewart’s sullen boss Happy Doug on 3rd Rock from the Sun.
In 2002, Jim was cast to star in the ensemble Western drama Deadwood, as Whitney Ellsworth, a goldminer whom he often describes as “Gabby Hayes with Tourette syndrome”, a character who transformed from a filth-covered reprobate to a beloved and stalwart figure of the community, and married the richest woman in town. Ellsworth originally did not have a first name, but Jim requested he be named Whitney Ellsworth, after the producer of George Reeves’s Adventures of Superman. During this time he continued his long research for the Reeves biography, and in 2005 served as the historical and biographical consultant on the Ben Affleck feature film about Reeves’s death, Hollywoodland.
In 2006, Jim starred in the shows John from Cincinnati and Big Love; but more importantly, he landed the beloved role of veteran hunter Bobby Singer on Supernatural, a role he later reprised in The Winchesters spinoff series.
He later played Sheriff Charlie Mills in the CBS prestige limited series Harper’s Island and gun dealer Lawson on Breaking Bad and its prequel Better Call Saul, before receiving acclaim as Sheriff Shelby Parlow on FX’s Justified. Following this, Jim featured in Guillermo del Toro’s gothic ghost story, Crimson Peak, playing a role Guillermo specifically wrote for him. He later teamed up with Guillermo again for Nightmare Alley.
Jim has featured in many other films and TV shows, and as of mid-2025 has appeared in over 110 stage productions.
His memoir about the year after his wife’s 2003 lung cancer diagnosis, titled Life’s That Way, was purchased in a preemptive bid by Putnam/Penguin publishers in 2007. Prior to publication in April, 2009, it was chosen for the Barnes & Noble Discover Great New Writers program.
Since 2018, Jim has portrayed Secretary of Defense, then U.S. presidential candidate and finally U.S. President Robert “Dakota Bob” Singer on the Amazon series The Boys, produced by the creator of Supernatural, Eric Kripke. Funnily enough, his characters on The Boys and Supernatural share the same name.
