Every movie presents its challenges.

I took a year of karate. It was like obligatory... every kid was taking like one year of karate and one year of piano in my town. It was Bruce Lee and Liberace. But I was not a white belt. I graduated. I had a colour belt - but that's all you need to know. It could have been black, it could have been yellow, or it could have been anything in between.

I'd just like to be in films that I would like to see. I think of myself as an entertainment arsenal. Like I have my acting bazooka and my music machete. And you don't know what I'm going to come at you with.

The thing is, the kids always rebel against what the parents try to push on them so I'm going to pretend like I don't want my son to hear the rock. I'm going to listen to it only in my private chambers. He'll hear echoes of it and say: "What was that you were listening to papa?" And I'll say: "Nothing son, you're not ready."

I'm not thinking about forcing my kids to watch my movies. It's always awkward when someone says: "Hey, I wrote a song, can I play it for you?" That would be the dynamic, if I was like: "Hey, you're my son, watch my work!" I don't want to put them in that awkward position. Just because when they get older, that's when I'm worried, that they'll judge me and say: "Yeah, my father's ******* Jack Black. He was in that cheesy movie." So, I'm going to keep it all high quality. It'll be a quality controller.

I'm always looking for talented people that I want to collaborate with.

I'm used to being crazy and "rock-n-rolly", which is a little different than this world. For me, it was a chance to stretch a little bit.
