I love the idea of a super villain that doesn't wear a cape, that doesn't wear a super suit.

Every director should take an acting class. At least one. You know, you panic with actors. It's like, "Okay, this is back in college, I know how to talk to these guys. I know their vocabulary, and I get what they're saying back to me." So basically to learn the vernacular of acting, that's very important.

I always have humour in my action movies. I think characters that make jokes under fire are more real. It somehow helps put you in their shoes.

I had my group of friends, and they stayed my group of friends, they were good about that. We all started to succeed at the same time, so that sort of took the curse off it. I didn't have a bunch of people scowling at me and being potentially jealous. I just had good friends who I was able to help, and they helped me. Yet it eventually came to feel debilitating.

When you only have $15 million, you have to talk about something interesting. You can't just cut to a helicopter exploding.

I have a shoebox: for ideas, fragments, snatches of conversation I hear. I scrawl it down, throw the scraps in the box. Every time I start a new script I start picking through the pieces. Suddenly you get five pieces together and think: this is almost the first Act of a movie, if I flesh it out a bit.

The worst of the action films are the ones where everything is one shout from beginning to finish. And there's no differentiation between beats, like small or big, or quiet or expansive. It's all just one loud shout.
