For his latest film, Dom Hemingway, Jude Law packed on 20 pounds to play an ex-con and admits he got used to overindulging!
“It was tough to turn it off at the end,” he shares. “It was allowing myself to say ‘yes’ to everything — ice cream . . . burgers . . . all the wrong stuff.”
And although director Richard Shepard appreciated the star's commitment to the role, he was more focused on keeping him alive!
“He was drinking, like, 10 sodas a day, drinking nonalcoholic beer, which is disgusting, and he was pasty-faced [from] smoking," says Richard of his leading man.
"I was like, ‘Just please don’t have a heart attack until we are done filming.’”
