Michael Fassbender Cannot Stop Cracking Jokes During Interview

— -- Michael Fassbender makes his highly anticipated debut in the action-packed video game flick "Assassin's Creed" this weekend.

He stopped by ABC's "Popcorn With Peter Travers" to talk about his dual roles in the film.

But first Travers asked him, "Are you now a major video gamer?"

"I'm actually entering in the competition for best gamer in the world," Fassbender joked. "I can actually play it blindfolded. That's the crazy thing. Because I know it so well now."

But Travers wasn't having it. "Liar, liar pants on fire," he said.

"No, I was terrible. I just kept going into the corner and trying to crawl up a wall. But I enjoyed it," Fassbender confessed.

Fassbender plays two characters, Callum Lynch and Aguilar de Nerha, which were created for the film. He explained that there are two timelines in the movie — past and present — and a machine is used for time travel.

"It's like a genetic DeLorean," he said.

The action in the film is intense. And while Fassbender looks perfectly chiseled in the movie, Travers jokingly questioned who actually pulled off all the big action scenes, saying, "In this movie, I don't know if it's you or the stunt guy."

"It's me. You know this," said Fassbender. "A lot of the jumping, you're right, I didn't do. But I had a foot massage usually on a day like that in my trailer. You know, maybe had something to eat. Sometimes I didn't even bother going to set if I knew there was going to be someone jumping."

"Why shouldn't you just Skype it in?" Travers asked.

"Exactly, there was a nice pool at the hotel," said Fassbender, playing along. "No, I ended up doing 95 percent of the fights myself."

Still not convinced, Travers joked, "Fight scenes are one thing, but insurance companies don't like it when their leading actor is putting himself in danger."

"They don't mind, to be honest," Fassbender said.

"With you, they don't. It's only [Leonardo] DiCaprio," Travers joked.

"Yes, exactly. They're like, 'Just make sure Leo doesn't do the jump. That guy — what's his name, Fassbender? I can't even pronounce it. He can do it,'" Fassbender said.

Throughout the interview, Travers and Fassbender went back and forth with quick comebacks.
