Christian Bale looks unrecognisable for Dick Cheney role

In order to develop the proper body type and gain weight, Bale told variety.com: "I've just been eating a lot of pies."

Bale has gone through shocking body transformations during his career, including losing 65 pounds and eating only an apple and a can of tuna a day for "The Machinist", and later bulking up to play the superhero Batman in filmmaker Christopher Nolan's trilogy.

The upcoming film is currently untitled and is yet to go on the floors.

Adam McKay is set to direct and the film will also star Steve Carell as Secretary of Defense Donald Rumsfeld, and Amy Adams is set to play Lynne Cheney.
