I'm done with effects movies for now. When you do a movie like 'Transformers,' it can feel like you're doing three movies at once - which is tiring.

We don't make movies for critics. I've done four movies; there's millions upon millions upon millions of people who've paid to see them. Somebody likes them. My greatest joy is to sit anonymously in a dark theater and watch it with an audience, a paying audience.

Maybe I have just a younger voice than many other directors.

I was talking to one of the writers about our target audience, and he was insulted that I used that term. But if you're given $60 million to make a film, you'd better know who your target audience is. That's who's going to pay back the bills you run up.

What I look for in a script is something that challenges me, something that breaks new ground, something that allows me to flex my director muscle. You have got to think fast in this business, youve got to keep reinventing yourself to stay on top.

There are things that I invented - the creaky geriatric robot that is always grumpy, for example, or the little wheelie guy, he's not in the Hasbro lore. But kids love that stuff - this little guy as a pet on a chain. They gravitate towards it.

I like to have an active set and a fun set. I keep my days to a decent hour; I don't go overtime. Do I beat people up? I beat people up in that they know I like to shoot fast. And they know I like to be efficient. And that I like to leapfrog.
