A biographical film, or biopic (/ˈbaɪoʊpɪk/; abbreviation for biographical motion picture), is a film that dramatizes the life of a non-fictional or historically-based person or people. Such films show the life of a historical person and the central character’s real name is used. They differ from films "based on a true story" or “historical drama films" in that they attempt to comprehensively tell a person’s life story or at least the most historically important years of their lives.
Because the figures portrayed are actual people, whose actions and characteristics are known to the public (or at least historically documented), biopic roles are considered some of the most demanding of actors and actresses.Ben Kingsley, Johnny Depp, Jim Carrey, and Jamie Foxx all gained new-found respect as dramatic actors after starring in biopics: Ben Kingsley as Mahatma Gandhi in Gandhi (1982), Depp as Ed Wood in Ed Wood (1994), Carrey as Andy Kaufman in Man on the Moon (1999), and Foxx as Ray Charles in Ray (2004).
In rare cases, sometimes called auto biopics, the subject of the film plays himself or herself: Jackie Robinson in The Jackie Robinson Story; Muhammad Ali in The Greatest; Audie Murphy in To Hell and Back; Patty Duke in Call Me Anna; Bob Mathias in The Bob Mathias Story, Arlo Guthrie in Alice's Restaurant; and Howard Stern in Private Parts.
