Shia LaBeouf slashed his own face with a knife and had a tooth removed in a bid to make his Fury character more realistic.
The US actor's co-star, Logan Lerman, has said that LaBeouf decided to take matters into his own hands when he failed to see how his make-up 'cuts' looked real.
"They were putting cuts on Shia and I said, 'Yeah, yeah, it looks good'," Lerman told British GQ. "And Shia was like 'No, it doesn't look real'."
The 22-year-old was not expecting what happened next. "He walks out into the hallway and says, 'Hey man, wanna see something fun? Check this out...' and he takes out a knife and cuts his face," Lerman continued.
"For the whole movie he kept opening these cuts on his face. That's all real."
