The 49-year-old actor, who plays Vision in the Marvel Cinematic Universe, appeared on The Late Show on Wednesday, March 3, where host Stephen Colbert wanted to know how much of his character's impressive chest belongs to the actor himself, and how much is Hollywood smoke and mirrors.
"I'm going to get very specific with you now," Paul replied. "About 42 inches of it is my chest. About eight inches just isn't. But it's not digital. It's a suit that, you know, you wear. They they give you a muscle suit."
The host responded with delight in the knowledge that he doesn't need to be quite as envious as he had been about the A Beautiful Mind star's physique. However, this doesn't mean Paul could just indulge whenever he felt so inclined.
"But the interesting thing is what you discover, is that you can't join in the sort of COVID pandemic banana bread-eating phantasmagoria," Paul continued. "Because when you wear the muscle suit, and you have a banana bread belly, it's very obvious. The jig's up."
Stephen appeared surprised that the film's producers couldn't find a way to digitally give the performer the midsection of his dreams.
"Maybe they can!" Paul replied. "I mean, for god's sake, Mark Ruffalo—you couldn't pull him away from the craft service table." This led both the host and guest to enjoy a hearty round of laughter, seemingly implying that Paul was kidding about Mark's appetite.
Then again, turning into the Hulk would make anyone hungry for an extra slice of banana bread.
