The Mayans, the wise race of ancients who created hot cocoa, set December 21st, 2012 as the end date of their Calendar, which the intelligent and logical amongst us know signifies the day the world will end, presumably at 12:21:12am, Mountain Time. From now until zero date, we will explore the 50 films you need to watch before the entire world perishes. We don’t have much time, so be content, be prepared, be entertained. The Film: Back to the Future (1985) The Plot: 1980s styled Michael J. Fox (see: feathered hair, acid washed jeans, high tops) stars as every-kid Marty McFly who accidentally gets sent back to the 1950s via a time-traveling DeLorean invented by his eccentric cohort, Dr. Emmett Brown (Christopher Lloyd, in one of his best scene chewing roles to date.) While going back in time may seem like a cool idea, Marty quickly realizes that altering the past can have serious effects on the future. Finding himself suddenly 30 years in the past, Marty discovers he must keep his now teenage parents’ relationship on track or else he will risk erasing his own future. As Doc would say: “Great Scott!”
