In the footage, which you can watch above, Dwayne Johnson looks unrecognizable as MMA fighter and two-time UFC Heavyweight Tournament Champion Mark Kerr. We see Kerr in multiple fights, as well as talking about his ethos towards the sport. Johnson, of course, started out as a professional wrestler, so this seems like a role that was made for him.

When The Rock first came to Hollywood from WWE — back when he was really still only known as The Rock, he didn’t start going by Dwayne Johnson until a couple year slater — he shrunk down his massive wrestling physique so he could play slightly more plausible real people in films.
