The trailer for the upcoming film The Smashing Machine starring WWE legend Dwayne "The Rock" Johnson was released by the A24 production company Tuesday. In The Smashing Machine, The Rock portrays Mark Kerr, who was a mixed martial arts pioneer in the late 1990s and throughout the 2000s, competing in the UFC and Pride.

In The Smashing Machine documentary, graphic footage is shown of Kerr injecting narcotics in a bid to numb his pain. His girlfriend and later wife, Dawn, who will be played in the film adaptation by Emily Blunt, pleaded with him to get clean. In 1999, Kerr was hospitalized after overdosing on narcotics, but returned to fighting the following year.
