The ancient Mayans believed that the world would come to complete ruin in the year 2012. Present day Hollywood predicts this could be a box office success in Summer 2009.

It has already been announced that John Cusack will star in the Roland Emmerich film and now Woody Harrelson has revealed to MTV that he has joined the cast of the upcoming apocalyptic thriller 2012 as well.

“I play a guy who’s been talking for a long time, the whole world thinks he’s crazy,” Harrelson said of his character. “But he’s been talking that there’s gonna be hell to pay for what’s been going on ecologically and everything.”

Harrelson doesn’t know why they thought of him for the role, but for those of us who know of his outspoken activist ways, it seems a very natural fit.

Other actors due to star in 2012 include Thandie Newton, Danny Glover, Amanda Peet (fortunately the subject of vaccines isn’t in the storyline), Oliver Platt, and Chin Han.
