Spaceballs, Interstellar, the difference is all in the trailer editing. Well, that and about $100 million dollars. Mel Brooks' cult classic Spaceballs might not be a mind-bending piece of science fiction as is, but that's just because it's trailer didn't have the right score and screen edits. Add in some brooding music and all of a sudden John Candy seems a lot deeper and Rick Moranis seems like the most sinister villain in the galaxy.
