This is Chris Pratt in the role of Mario Mario. Even though Mario is Italian, Chris Pratt sounds literally nothing like him due to his extreme American accent. This is an entirely ironic casting, and Chris Pratt somehow knows nothing about Mario games. He says he spent hours stomping Koopas in the original Mario Bros arcade game, which is just dumb because they can't be stomped in arcade Mario Bros. Chris Pratt is clearly reading off of a script when he talks about Mario. It's just hilarious
