2. The Room
Tommy Wiseau, director/producer/writer and star of The Room, is a legend in cult cinema. Upon first glance at his film's frightening movie poster, you may think, "Is this a thriller about a murderous wackjob with a wonky eye?"
Why, no! It's about one man with a golden heart, large bank account, impressive duds, and enormous talent in the bedroom, who is then betrayed by everyone he knows.
It's a classic, heartbreaking tale. When The Room was initially released, it was marketed as a dark drama reflecting on how everyone you love will hurt you.
After it became a cult classic, due entirely to the absurdity of the plot, characters, set, and general exhibition of the entire movie, Wiseau then changed his mind and said he had intended for it to be a black comedy all along.
He could have said that it was meant to be an arthouse karate movie and we'd still watch it anyway.
