The Smashing Machine,” written and directed by Benny Safdie, stars Dwayne Johnson and Emily Blunt. The biopic will be released in October.

Dwayne Johnson stars as former wrestler and UFC star Mark Kerr in a new trailer for Benny Safdie's "The Smashing Machine."

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.
