The film is based on Greg Sestero and Tom Bissell's non-fiction book of the same name

Tommy Wiseau and Greg Sestero become friends after meeting each other in an acting class in San Francisco. Sestero moves to Los Angeles and signs on to appear in Tommy’s new project. Financed with his own money, Wiseau writes, directs and stars in "The Room," a movie that becomes a cult classic – for all the wrong reasons.
