Jon Bernthal interview talks about Logan Lerman

From the interview:
Shia went the extra mile, cutting his face and taking the tooth out. Was that something you admired or do you feel he'd gone too far?

I feel like Shia is a brilliant actor and he's brilliant in this role. His commitment was beautiful, but at no point did I sort of look at him and say, "Oh wow, he's crossing the boundaries." He helped to make it dangerous on set. I helped to make it dangerous on set. Brad helped to make it dangerous on set, that's what we were doing. I don't think his commitment was any different than anyone else’s, it's just what we were doing. Yeah, he pulled his *beep* tooth out. I've got to say, when I look at Logan and his commitment, there's no question this process, both who they were before this started, what their upbringing was, who they were and what they experienced, nobody went through nearly as much as Logan. Nobody. He got the *beep* beaten out of him every day, he bore the brunt of all of our *beep* and ridicule because that was the character. He's younger than all of us, he's less experienced at fighting than all of us, and never once did he complain, never once did he break down. And I thought that Logan's commitment blew me away and I thought that his toughness was unparalleled.
