21. 'The Room'
Most cult movies are weirdly wonderful, but every once in a while one comes around that's weirdly terrible. That is definitely the story of The Room, an inadvertently hilarious 2003 movie by the mysterious Tommy Wiseau. Somehow or another, he put together a $6 million budget and made a movie that ranks high on the all-time worst list, complete with horrid acting, continuity flaws and even a breast cancer diagnosis that seems to have no bearing on the plot. Such a movie might seemed doomed for obscurity, but it eventually gained a cult following on the midnight circuit. As unlikely as it may seem, The Room has become the latest Rocky Horror Picture Show, and it currently screens at midnight more than any other movie in the country.
