For years I was doing the excruciating weightlifting of writing scripts - but then I stayed thin and someone else got all the muscles.

An action film can have too much action; picture an equaliser on a stereo, with all the knobs pegged at 10. It becomes a cacophony and is, ultimately, quite boring.

Probably my favorite piece of music, as an album taken as a whole, is Bruce Springsteen's 'Greetings from Asbury Park.' I just think it's incredibly pure. It's a sound that sort of broke new ground, and I think it paved the way for a hundred people that sound very similar.

People would say, "Well yeah, if I wrote action films, if I wrote the trash that you write, I could make millions too. But I want to write my real movie about these Guatemalan immigrants, and how they hid under a truck for 300 miles." And that's fine. I'd love to make that film too, but to dismiss everything I did just because it's action seems wrong.

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.

Any time anyone fires bullets in an action movie that don't hit the target it immediately undermines the movie.

I think it's an obligation to make a movie full, so you have to see it twice to get all the moments.
