Yes I included a bad movie on here, the same list with Citizen Kane and The Godfather. This movie was made by a film crew who knew how to physically make a movie, but failed so horribly that it's become a cult classic. You will also hear a lot of film major in-jokes referring to this movie and there will likely be a midnight screening on your campus at some point.
