Donnie Darko (2001) - starring Jake Gyllenhaal, Maggie Gyllenhaal, Patrick Swayze & James Duval. 'A troubled teenager is plagued by visions of a large bunny rabbit that manipulates him to commit a series of crimes, after narrowly escaping a bizarre accident.' Time-traveller & cult movie.
'The Rocky Horror Picture Show' has become a classic film and has gained a massive following. Around Halloween every year, different theaters screen the movie, while audience members sing, dress up and even act out the movie. I know its wierd yet fun.
