Aaron Taylor-Johnson Says He 'Didn't Drink a Drop of Alcohol for 2 ...

Aaron Taylor-Johnson knows how to commit to a character.

The star of Kraven the Hunter shared the rigorous regimen he followed to prepare for the action film on the Dec. 11 episode of Stars on Sirius XM.

Taylor-Johnson said he was very selective about what he consumed in the years leading up to the film — which comes out Dec. 13 — to maintain the protagonist's muscular physique.

"I didn't drink a drop of alcohol for two years," he said. "I stayed off of rubbish and crap food, stuff like that. I was in the best shape possible."

Taylor-Johnson said his "insane" and "disciplined" training regime lasted roughly six months. But the process behind the movie lasted years — and during that time he worked on other films like Fall Guy and 28 Years Later.

Those projects required a different look, he said, and transitioning between the films meant he had to be flexible with his appearance.

"I have to naturally slim down, for playing more ... more normal roles," he said, referring to characters who were not as ripped as Kraven. He added, "No one needs to see those arms all the time."

He continued, "I had to be kind of ready and conditioned in a way where I could then quickly put on muscle mass again and train hard between [projects]."

"Funnily enough, my craving for candy kind of disappeared, in a weird way," he said. "I think I've sort of reconditioned ... you know, bag of chips, stuff like that — I just don't actually gravitate to anymore."

But indulgences like pizza, pasta and beer are definitely still appealing to him, he said. They're "life's pleasures, I think."
