Last time we saw Lucas Till — in the Johnny Cash biopic Walk The Line — he was suffering through an unfortunate run-in with a buzzsaw. You can bet he fares quite a bit better in his new role: co-starring with Miley Cyrus in this weekend's Hannah Montana: The Movie. As her love interest, no less.

Till seems to have no trouble playing the square-jawed hero type. In real life, he says, he's been rocking out to Metallica's Black Album and working on his Brazilian jujitsu techniques. But there's still something, or someone, that makes him sweat: Miley herself. 

As he reveals in this interview — that's Radio Disney's Ernie D throwing out some questions for Buzznet(!!) — he had a tough time staying cool when he went in to audition with the pop star. Before that, he went on what he calls the "actor diet" — he couldn't eat for a week. He also seems to confirm her reputation for practical joking: he says he didn't even try to sneak anything past her for fear of being caught. But then again, he could've just used the jujitsu.

Of course, the irony is that just as he's about to show the world how well he can play the role of Miley's significant other, all anyone seems to want to talk about is his crush on Taylor Swift.

His next real role, though, is in an upcoming Jackie Chan movie. Again, the jujitsu's going to come in handy.

Really, what does he have to be nervous about?
