Christian Bale’s weight has fluctuated intensely for various movie roles, the actor losing over 62 pounds for The Machinist, and growing out a pot belly for American Hustle.

For an upcoming role, portraying Vice President Dick Cheney upcoming biopic Backseat, the Batman actor has once again pilled on the pounds.

Asked about putting on the weight at the Toronto Film Festival, Bale smirked and said: "I've just been eating a lot of pies.”

Backseat sees Bale reunite with The Big Short director Adam McKay and actor Steve Carell, who will play Secretary of Defense Donald Rumsfeld.

Bale’s American Hustle co-star Amy Adams stars as Lynne Cheney, while Sam Rockwell and Bill Pullman will play George W. Bush and Nelson Rockefeller, respectively.

Cheney served as Bush's VP between 2001 and 2009 and was a key player in US foreign policy during that time, particularly with regards to the wars in Afghanistan and Iraq.

Meanwhile, Hostiles reaches cinemas before Backseat. Set in 1892, the film follows a US Army Captain — played by Bale — who reluctantly agrees to escort a dying Cheyenne war chief and his family back to tribal lands.
