He once lost almost five stone for his part in movie role, The Machinist - and Christian Bale has altered his look dramatically for a part once again.
The actor, 44, has gained 3st 4lbs to play George W. Bush's Vice President Dick Cheney, 77, and shows off his body transformation in a new trailer for new film, Vice.
Movie - Hollywood - A-lister - Brad - Pitt
The movie has been produced by Hollywood A-lister Brad Pitt and explores how a bureaucratic Washington insider quietly became the most powerful man in the world as Vice-President to George W. Bush, reshaping the country and the globe in ways still felt today.
As well as the weight gain, the first trailer sees Christian shave his head and pluck his eyebrows, something he had to do daily. Sam Rockwell plays the 43rd president.
Trailer - Quail - Accident - Cheney - Friend
The trailer also includes that 2006 quail hunting accident, in which Cheney inadvertently shot a friend in the face.
The blink-and-you-miss-it clip briefly shows Cheney with his wife, Lynn, portrayed by his American Hustle co-star Amy Adams.
Movie - December - US - Release - Date
The movie is slated for December 25 in the US. No release date has been set elsewhere.
Bale is known for his extreme physical changes for roles.
Machinist - Weight - Batman - Bruce - Wayne
Back in the early 2000s, he lost 62lbs to star in 2004's The Machinist, before beefing up to an even heavier weight to play Batman's Bruce Wayne.
In The Machinist, he famously only ate one apple and drank water, as well as one cup of coffee a day, with the occasional whiskey.
