Kevin Hart is jacked and ready to play a rough and tough mercenary in his new sci-fi action flick “Borderlands.”

“Extra” spoke with Kevin and his co-stars Jamie Lee Curtis, Édgar Ramírez and Florian Munteanu and director Eli Roth about the movie at the 2024 San Diego Comic-Con.

Hart muscled his way through the training… without any help from his frenemy Dwayne “The Rock”Johnson

Hart joked, “I didn’t have that chump help me at all. That low-grade, low-level action guy. I needed the real deal, the real stuff.”

Instead, Kevin turned to some Navy SEALs for the heavy lifting.

He shared, “Did a lot of test-battle stuff. Put me in the field, no real concept of what was gonna happen. Just a booм, and there I was. Just had to get on.”

Kevin’s kids got to visit set to watch him work, and he said, “My kids showed up ready, first scene. That’s how I got to know what I was doing, if it was real, if I was in there in the nitty-gritty.”

“Borderlands,” based on the billion-dollar global smash video game series, centers on Cate Blanchett as an infamous outlaw and a team of misfit heroes, including Kevin and Jamie, who must protect a powerful girl played by Ariana Greenblatt.

“Borderlands” is in theaters August 9.
