Dwayne Johnson undergoes dramatic transformation in the first trailer for The Smashing Machine, a biopic about UFC heavyweight champ Mark Kerr. A24 pulled the curtain back on the drama Tuesday morning.

Benny Safdie, of the two Safdie brothers who co-directed and wrote “Uncut Gems” and “Good Time,” makes his solo directorial debut on the film.

The cast also includes Oscar nominee Emily Blunt as Kerr’s wife Dawn Staples, Bas Rutten, Lyndsey Gavin and Oleksandr Usyk.

“The Smashing Machine” is Johnson and Blunt’s second collaboration after Disney’s “Jungle Cruise” in 2021, and they’re set to next team with DiCaprio on Scorsese’s Hawaiian crime thriller.

Johnson previously said that he wanted to work with Safdie on “The Smashing Machine” because “Benny wants to continues to push the envelope when it comes to stories that are raw and real, characters that are authentic and at times uncomfortable and arresting. I’m at a point in my career where I want to push myself in ways that I’ve not pushed myself in the past. I’m at a point in my career where I want to make films that matter, that explore a humanity and explore struggle [and] pain.”

Kerr and Safdie serve as co-writers.

Safdie, Johnson, Danny Garcia, Eli Bush, Hiram Garcia and David Koplan are producers. Tracey Landon executive produces.

“The Smashing Machine” comes to theaters on October 3.
