They say that everything, in cinema at least, has been done. There is nothing new to explore, no new ground to be trodden, as this is the era of the re-make; everything these days is an update on something that's already been done, whether it's reimagining a hero we love, adapting a novel that's caught the world by storm, or even just setting a common story in space. Well, certain films want to argue with that. Certain directors think completely outside of the box, and I'm not just talking about The Human Centipede or Little Otik, a Czech film about a couple who can't have children, so they carve a baby out of wood. Some films are so fundamentally fascinating, that they've made their money on the concept, and not on the plot; these are films that sound so original that you don't care who's in it, you're going to see it. And it's this type of film that'll make any critic eat their hat before declaring that nothing is original. Here are ten movies with fantastic premises, some of which pushed the boundaries of cinema, and some of which just made for compelling movies. Got any more to add? Comment below!
