Bale’s Cheney replies: “George, I’m a CEO of a large company, and I have been secretary of defence, and I have been White House chief of staff.

Vice was directed by Adam McKay and stars Amy Adams as Lynne Cheney and Steve Carell as Donald Rumsfeld.
It is not the first time Bale has dramatically changed his looks for a part.
He shed more than 60lbs to play troubled Trevor Reznik in 2004 psychological thriller The Machinist, then bulked up to play the caped crusader in Batman Begins in 2005.
In 2010, he lost weight once again for David O Russell’s The Fighter.
