Jake Gyllenhaal is the latest actor to drop major weight for a movie, but he says it’s really not that different from prepping for any role.

“I think [I’ve lost] probably a little over 20 pounds, something like that,” the actor, 32, told PEOPLE Monday on the red carpet at the Hollywood Film Awards, where he looked noticeably thinner as he was honored for his role in Prisoners.

While he may look different, his approach hasn’t changed as he prepares for Nightcrawler, Gyllenhaal said.

“It’s no different than getting into character for anything. It’s more about believing where you are and being present where you are,” he said. “Who’s to say what the process is? I have a strange one .. but I love what I do.”
