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.

Directed by Benny Safdie, the biopic chronicles Kerr’s rise as a two-time UFC Heavyweight Tournament Champion and his struggles with addiction and personal challenges.
