John Cusack and Amanda Peet Talk '2012'

John Cusack and Amanda Peet try to outrun the end of the world in '2012,' and they're telling ET all about it.

We caught up with John and Amanda, along with their co-star Chiwetel Ejiofor, at Yosemite National Park to talk about the disaster film, directed by Roland Emmerich.

'2012' follows the premise that, according to the ancient calendar created by the Mayans, the world will end in December of the year 2012. In the film, when that date arrives, all humans on earth are faced with global cataclysms.
