Michael Madsen’s performance in ‘As Long As You Love Me’ was nothing less than stellar and when MTV caught up with the Sin City actor, he had a lot to say about working with Justin Bieber for the video calling him “very respectful and decent.”

“I didn’t exactly enjoy slapping him around,” he said. Madsen continued, “Had he been a prick, had he been a brat, you know, I might have had fun with that. But he was actually, he was the opposite.”

He said: “I think that I’ve been around enough to know I can tell if somebody isn’t really doing their job or taking what they do seriously. And I could tell from early on in the morning that he was. He wanted it to be right. He wanted it to be specific and had a good car, a ’68 Charger. That’s a pretty b—-ing car, you know? I saw that da– thing parked in front of the house and I went ‘Wow, I hope that’s mine.’ But they put me in a Rolls Royce; not too bad at all.”

“He had good eye contact,” Madsen noted. “He was focused. He didn’t have a double. I think he should leave the acting up to me. He can sing though. See I can’t do that. It goes both ways. He can sing his head off and he’s da– good at it, and I couldn’t get close to that. He does his thing, and I do mine.”
