Dwayne Johnson is soon heading to theaters in what might be the most dramatic role of his career so far.

Dwayne Johnson is soon heading to theaters in what might be the most dramatic role of his career so far. In “The Smashing Machine,” Johnson will play MMA and UFC fighter Mark Kerr, who was the subject of a 2002 HBO documentary that chronicled his substance abuse and explored the brutality of the sport to which he’d dedicated his life. The new trailer for “The Smashing Machine,” released Tuesday by A24, hits on those themes and more, also highlighting Kerr’s tumultuous relationship with his girlfriend, played in the film by Johnson’s former “Jungle Cruise” co-star Emily Blunt. “Winning is the best feeling in the word,” Johnson as Kerr says in the trailer. “It’s 40,000 people in there cheering you on. There’s no other high like it in the world.” Though he has yet to speak specifically about his physical transformation for the role, Johnson appears to have used facial prosthetics to help him more closely resemble Kerr, whose 12-year career took off in the late ’90s. The new film marks a more dramatic turn from Johnson, who is best known for his high-octane action fare like “San Andreas,” “Skyscraper,” and is certainly not what audiences might be accustomed to seeing from him.
