Miles Teller is working hard for that body!
The actor is set to play real-life World Champion Boxer Vinny Pazienza in "Bleed For This," a role that required a lot of time in the gym.
The "Divergent Series: Insurgent" star talked about his transformation during a recent interview on "The Tonight Show," after Jimmy Fallon showed before-and-after photos of his chiseled physique.
"This is just your head on my body," the comedian joked as the audience cheered. "Does that not look like me?," he asked as he covered Miles' face with his finger.
Teller also sports a mustache in the movie, which is something he struggled to grow!
"I take a long time to grow some facial hair, man," he admitted. "Everyone has their strengths. I'm a great dancer, I have good hair, I don't have, like, weird body hair."
"I would love to grow a Tom Selleck mustache!" he added.
