Jason Momoa Explains Why He Chugged Beer to Feel 'Really Swole' on 'Aquaman 2' Set

The world may be full of uncertainties, but one thing is for sure: Jason Momoa loves Guinness. The Game of Thrones star spoke to Men’s Health just ahead of St. Patrick’s Day to promote a new live-action commercial he wrote and directed for the beer brand. During their chat, Momoa revealed why chugging a Guinness during a scene in Aquaman and the Lost Kingdom was vital for his physical well-being.

Momoa explained that because of his diet and heritage, he was having trouble looking properly “swole” on camera.

“It's a consistency thing. I’m half Polynesian. There's not a lot of Polynesians rolling around where you see veins popping out. It's a different body type,” Momoa explained.

“We're big. The abs are different for us, but we're big strong humans,” he went on. “Because you have no carbs and because the veins are restricted, all of a sudden you just look really swole and filled up, and your veins pop.”

Momoa recalled the on-set moment when he realized he needed a hearty brew. “I was like, ‘Just give me a Guinness.’ And I had been deprived for so long that I just cracked one, and both of my trainers were right in front of me, and they watched, and I just had one,” the actor said.

“You can see my veins…you can see everything just coming back to life,” he continued. “And they're like, ‘You're a freak. That makes no sense. You're a freak.’”

But Momoa told the crew that his love for Guinness transcends the boundaries of conventional wisdom. His mother, who makes an appearance in his Guinness ad, was the person who stoked his love of the creamy beverage.

“I'm like, ‘My body—it's what it loves. It's what it likes,’” Momoa told the set.
