"He'd beaten the s--- out of me so many times."
The actors played brothers in the 2014 psychological drama about Olympic wrestler Mark Schultz (Tatum), and at one point Ruffalo's fellow wrestler and coach Dave is tasked with walloping the athlete. Before the take, Tatum told Ruffalo to really let him have it and "get it over with."
"He did ask me to slap the s--- out of him, and it was easy to do because he’d beaten the s--- out of me so many times," Ruffalo said between bites of spicy wings on Thursday's episode of Hot Ones. "It was four months of learning to wrestle together, and he has like 30 pounds on me."
The Poor Things actor continued, "So when it came time to smack the s--- out of him, I, like, came from Alabama."
Tatum recalled Ruffalo popping his eardrums at the 2014 Cannes Film Festival. "All of a sudden it’s just making a screeching noise. I can’t hear anything," he said, noting that his reaction on camera was genuine. However, he said, "Eardrums heal, so I’m fine.”
The actor's ears weren't his only body parts roughed up during filming. "I’m pretty sure I broke my hand in the movie in the training,” Tatum said. “You’re just throwing bodies around and you get caught in different angles.”
Directed by Bennett Miller, the Oscar-nominated film tells the real story of the murder of Ruffalo's Dave Schultz at the hands of John du Pont (played by Steve Carell), who was convicted for the crime in 1997. It begins with Carell's sports enthusiast and heir to the du Pont family fortune inviting Tatum's Mark to move into his estate to help form a wrestling team for the 1988 Olympics.
