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 a fresh perspective because it's fun to tell stories that are original and new in some way.

The greatest gift in life is the ability to think great thoughts and have the strength to take action so that those thoughts become reality in this wonderful and abundant world.

It's a mistake to just go make a movie where the whole thing is talking down to the kids like, "Ok, we gotta bring the IQ of this movie down because it's a kids movie" You don't have to do that, kids can laugh and parents can laugh at different parts and that's fun, and you see that with all of the great kids movies.

I just had a son and had to take him to the paediatrician and he measured his head and apparently he's in a group in which only 14 per cent of the population have a bigger head than him. Then she said: "Do you mind if I measure your head?" I said: "Go ahead." And she was shocked, because less than one per cent of the world's population has a bigger head than mine. So I guess that means I'm pretty full of myself. Or that I have a huge brain.

With the acting, it's somebody else's brainchild, and I'm just sort of helping flesh it out. There's a special satisfaction to being the brains behind the operation.

Funny songs, that’s my ticket. I can’t remember when it started or why it started, it’s just something that I NEEDED.
