Where the Buffalo Roam is a 1980 American semi-biographical comedy film which loosely depicts Hunter S. Thompson's rise to fame in the 1970s and his relationship with Chicano attorney and activist Oscar Zeta Acosta. Art Linson directed the picture, while Bill Murray portrayed the author and Peter Boyle portrayed Acosta, who is referred to in the film as Carl Lazlo, Esq. A number of other names, places, and details of Thompson's life are also changed.
Thompson's obituary for Acosta, "The Banshee Screams for Buffalo Meat," which appeared in Rolling Stone in October 1977, serves as the basis of the film, although screenplay writer John Kaye drew from several other works, including Fear and Loathing on the Campaign Trail '72, The Great Shark Hunt, and Fear and Loathing in Las Vegas. Thompson served as "executive consultant" on the film.
