The Room is a 2003 American independent romantic drama film written, directed, and produced by Tommy Wiseau, who also stars in the film alongside Juliette Danielle and Greg Sestero. Set in San Francisco, the film is centred around a melodramatic love triangle between amiable banker Johnny (Wiseau), his deceptive fiancée Lisa (Danielle), and his conflicted best friend Mark (Sestero). The work was reportedly intended to be semi-autobiographical in nature. According to Wiseau, the title alludes to the potential of a room to be the site of both good and bad events. The stage play from which the film is derived was so named due to its events taking place entirely in a single room.

Greg Sestero is an American actor, filmmaker, model and author, best known for his role as Mark in the 2003 cult film The Room, as well as for his well-received memoir The Disaster Artist, detailing his experiences making The Room, which itself was later adapted into a 2017 film.
