If you purely go by the featurettes and trailers released for Roland Emmerich’s 2012, you’d think the film was just John Cusack going to the worst possible places to be during the end of the world, and then racing away from the ensuing catacylsm in a series of different vehicles. Well, it is pretty much that, but there is a bit more to it as well. The film is in cinemas tomorrow, but if you want a bit more info on how they created the grand disaster of a 30-mile wide explosion when the entirety of Yellowstone National Park explodes/erupts, click below to take a look.
