Obscure movie facts you probably didn't know

There are many kinds of movie fans: the casual weekenders just trying to kill some time and hopefully get a few hours of mindless entertainment; those that come to appreciate the art of filmmaking; and, rarer still, those that are so obsessed with movies and every little factoid that they could easily mouth along with every line of movies that don't even make their top 10. The latter category are the folks that are absolutely crushing the movies section at group trivia—and probably the only people who'd already know these crazy film facts.
