December 21 marks the end of the world (or at least that's how some interpret the Mayan calendar), and we're getting ready for the apocalypse with a big screen celebration of all the methods by which mankind is doomed...DOOMED!

So what form will the apocalypse take? Virus? Nuclear attack? Zombies? Primates? Kevin Costner? Find out as we start on 12.12.12 with 12 Monkeys, and celebrate the end of it all with a special Science on Screen debunking of the film 2012 on 12.20.12. Plus, we celebrate the final countdown with a final countdown of the best post-apocalypse music videos!
