A biopic is a movie that's based on someone's life story. It might be about a famous person or an ordinary one.
You've probably heard of biopics without even realizing it! They're those movies that come out every now and then, like "The Imitation Game" about Alan Turing or "Walk the Line" about Johnny Cash. People make these films because they think there's an interesting story to be told. Sometimes a biopic is based on real events, sometimes it takes some creative liberties, but most of the time you'll see how someone lived their life on screen. These movies often get nominated for Oscars and other awards, which can help make them popular.
(film) A motion picture based on the life (or lives) of a real, rather than fictional, person (or people).
