Several years before taking on the role of Dick Cheney in Vice, Christian Bale met Donald Trump when the then real estate tycoon visited the set of The Dark Knight Rises, in which he starred.

Bale claims that he and Trump spoke, but that the future president mistakenly acted like he was actually Bruce Wayne, IRL. He of course played him in Christopher Nolan’s trilogy.

“I met him, one time. We were filming on Batman in Trump Tower and he said, ‘Come on up to the office,’” Bale told Variety on the red carpet at the world premiere of his new film, Vice. “I think he thought I was Bruce Wayne because I was dressed as Bruce Wayne. So he talked to me like I was Bruce Wayne and I just went along with it, really. It was quite entertaining. I had no idea at the time that he would think about running for president.”

ON HIS BODY

To become Cheney in Vice, he had to undergo a physical transformation and gain 40 pounds. (He also had to shave his head and bleach his brows). 

So how did he bulk up? By “eating a lot of pies,” he tells Variety. It’s not the first time he’s had to gain or lose a lot of weight for a role. He lost 63 pounds for 2004’s The Machinist, then gained 100 pounds of muscle in six months to play Wayne in Batman Begins. 

Vice opens December 25thand he is considered a frontrunner for Best Actor in the Oscars for the role.
