Dwayne “The Rock” Johnson, who began filming The Smashing Machine on May 21, plays the role of a WWE wrestling star, Mark Kerr in the movie, a real-life fellow wrestler and former two-time UFC heavyweight champion who rose to fame in the 90s.

Recently, the movie just released the first on-set picture of the actor, and he looks unrecognisable.

The film, which takes its name from Kerr’s octagon nickname, has Johnson in the lead role. Compared to his trademark bald head, Johnson has short hair and no tattoos.

With the caption, “First look at Benny Safdie’s THE SMASHING MACHINE starring @therock and Emily Blunt,” Johnson posted the image to his Instagram account.

The picture shows the actor sitting in a corner of the ring talking to two men during a fight; next to the ring is the MMA fighter’s then-girlfriend, played by his old Jungle Cruise co-star Emily Blunt.

Variety reports that Benny Safdie is directing the film, which will center on Kerr’s emotional challenges and professional accomplishments, particularly his prior addiction to opiates.

Kerr, 55, is a co-writer of The Smashing Machine and has been retired from professional fighting since 2010.
