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.

It was like a frat house for film geeks, the Pad O' Guys. That's what being at UCLA afforded me. So when one of us had some success - in this case, my pal Fred Dekker - he would reach down the ladder and help me up a rung, give my work to his agent to pass around to see if anyone liked it.

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.

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 only way you can stay on top is to remember to touch bottom and get back to basics.

The other thing being at UCLA was just being in California and around the movie business. Which I honestly believe, and I've told this to screenwriters, you have to do. You have to be there in order to write or direct movies.

I think the most important thing is to, without belligerence, stand up for what want. Argue compellingly if someone tries to change your script.
