Director and Oscar nominee Adam McKay talks about the making of ‘Vice’ on 'Popcorn with Peter Travers'

The director, known for his comedies, went a different route with "Vice."

Film director and Oscar nominee Adam McKay has made us laugh with films, such as "Anchorman," "Step Brothers" and "Talladega Nights."

But his newest film, “Vice,” puts aside the comedy to tell the backstory of former Vice President Dick Cheney.

McKay brought on actor Christian Bale, who gained more than 40 pounds to play the role of Cheney, McKay said.

“He definitely put on some weight. He definitely transformed,” McKay told Travers.” “It was one of the most breathtaking performances I’ve ever seen in my life.”

Travers asked if the Bush-Cheney era was a prelude to the current presidency.

“It could be. And we were shocked at how much it lined up with what is going on now," McKay, 50, told Travers. "Our idea is that we’re living in these times that are so ridiculous and almost beyond comedy. But at the same time so tragic. So we tried to combine both. We tried to have a movie that was tragic, heartbreaking, but also absurd and sort of falling over itself, kind of like the times that we live in now.”

McKay said the film also delves into how Cheney’s wife played a pivotal role in setting his path for the future.

“He got DUI’s and he was messing up his life. And it was really Lynne Cheney who kind of set him straight," McKay said. "If you want to look at the first act of Dick Cheney’s life, it’s really Lynne Cheney, a kind of whipsmart, really ambitious, strong, strong woman from Wyoming who said, ‘Get your act together.’ And that’s kind of what changed him.”

"I really believe that we all kind of do the best we can," he added. "And it's how that road gets twisty and turny that's the story."

"Vice" can be seen in theaters everywhere.
