Josh Brolin started his career in TV movies and guest spots on TV shows before getting a more notable role as Brand Walsh in the Richard Donner-directed movie The Goonies (1985). He was then offered the role of Tom Hanson in the series 21 Jump Street but turned it down to star in the series Private Eye (1987), which lasted half a season. The role of Hanson later went to Johnny Depp. However, Josh guest starred in Jump Street in a season one episode. He is perhaps best known for his role as Jimmy (or James) Wild Bill Hickok in the ABC western TV series The Young Riders, which lasted three seasons (1989-92). Although an ensemble piece, Josh's character increasingly received significantly more screentime than his co-stars.

Two other TV series he was involved in include the Aaron Spelling production Winnetka Road (1994) and Mister Sterling (2003). Both series were canned after only a few episodes. His extensive film work consists mainly of supporting, bad-guy roles. His biggest box office success to date was Paul Verhoeven's Hollow Man (2000),(in which he went against type, playing a hero) which grossed $191,200,000 worldwide.

He has done extensive theatre work in Rochester, New York and has appeared alongside mentor and friend Anthony Zerbe. His most recent film work includes the Planet Terror segment of the Quentin Tarantino/Robert Rodriguez collaboration Grindhouse, The Coen brothers' No Country for Old Men, and Ridley Scott's American Gangster.
