GSP formally retired in 2019 -- 2 years after his last fight -- and has repeatedly said a comeback is most likely off the table.
Now, he's focusing on acting -- reprising his role as the French mercenary Georges Batroc in the upcoming Marvel series, "The Falcon and the Winter Soldier."
Georges says he uses some of his skills from fighting to help him as an actor.
"Like in fighting, acting requires a lot of repetition, a lot of preparation. In fighting, you do a lot of those as well and very often when you fight, you find out your opponent is never as good as you think he is and he’s never as bad as you think he is as well. It’s always different."
The main difference ... GSP acknowledges the stakes are much higher in fighting.
“In fighting, you only get one take. If you zig when you should zag -- boom! It can cost you not only a loss but it can cost you obviously cerebral damage. Damage that can cause your death. It’s very dangerous."
"You say ‘I play basketball, I play hockey’ but you don’t play fighting. It’s not a game. It’s a sport but it’s more than a game. It’s a different kind of thing."
