With less muscle, the actor has lost 27 kilos to portray a mixed martial arts and UFC champion in his latest movie, The Smashing Machine.
The actor, in his first truly dramatic role, shares the spotlight with Emily Blunt and the film received a 16-minute ovation from the audience at its premiere at the Venice Film Festival.
"This transformation was something I was eager to do," he told 'The Hollywood Reporter'. However, the film disappoints by its lack of ambition.
