Channing Tatum recently revealed that a byproduct of playing a professional wrestler in Foxcatcher was sustaining some real life injuries.

Channing Tatum Injured On 'Foxcatcher' Set

Tatum, 34, admitted that when you’re in the thick of a training scene, it’s almost impossible to not subject yourself to a possible broken bone. “I’m pretty sure I broke my hand in the movie in the training,” the actor told Variety. “You’re just throwing bodies around and you get caught in different angles.”

While filming one scene in particular, Tatum urged Mark Ruffalo, who plays his brother and trainer in the film, to give him all he had – hopeful that they wouldn’t have to do too many takes. The plan worked, though it didn’t come without a price. “He pops my eardrum,” Tatum said, revealing the grimace caught on camera wasn’t exactly acting. “All of a sudden it’s just making a screeching noise. I can’t hear anything. Eardrums heal, so I’m fine.”

In yet another scene, Channing had no one to blame for his injury but himself. When his character loses his temper, he slams his head into a mirror. Channing over aggressively put his head completely through the prop and counted himself lucky for only coming out of it with a scrape. “I went through the wall on the other side,” he says. “I missed the stud by about four inches. I was lucky. But the cut on my head was real.”

Foxcatcher, directed by Bennett Miller and starring Tatum, Ruffalo and Steve Carell, premiered at the Cannes Film Festival earlier in the week to rave reviews and cheers from the screening audience.
