In San Francisco, 1998, 19-year-old Greg Sestero meets a mysterious man named Tommy Wiseau on an acting act with Jean Shelton. Shelton cuts off Tommy’s performance from a scene in “A Streetcar Named Desire,” but Greg is impressed with Tommy’s courage and the two become good friends. At Tommy’s suggestion, the two move to Los Angeles to try to create successful careers in the world of cinema.
Greg signs a contract with Iris Burton, a talent agent, while Tommy receives refusals from all sides, from agents to selection directors or Hollywood insiders. Greg then forms a relationship with Amber, a girl he knows at a night club, and Tommy begins to become jealous of his boyfriend; because he fails to find work, he is losing hope that he will become a renowned actor as he dreamed.
When Greg’s auditions begin to crumble, he shares his frustrations with Tommy, who then decides to create himself a movie in which both of them will appear. Tommy then writes a screenplay for a movie he calls “The Room”. Greg accepts hesitantly the role of Mark and the executive producer of the film. They rent a production house, and Tommy insists that all production equipment is bought and the frames are shot on 35mm film and HD Digital simultaneously, very expensive and not necessary.
