There's big studio films I didn't want to do. I didn't want to go through the hoops and ladders. I wouldn't have been able to work with the directors I've worked with if I did those studio films.

See, the 'On the Road' that came out in 1957 was censored. A lot of the honesty of it, the bitter honesty, is in the original scroll version that came out in 2007 on the 50-year anniversary. Back then, there was so much post-Second World War fear that was imposed on everybody - 'You must live life this way' - and these guys were bored.

I used to be sick of the backroads of Minnesota. I had to drive 30 miles to get home every day, take the schoolbus for two hours. But to drive through America and see the backroads, from Nashville to Memphis, Lovick to New Mexico, was incredible. It was probably the greatest trip of my life.

I think the only thing harder for a parent is having to sit down and watch you do a dying scene. I've died in three films, and my mom begs me, "Just tell me you don't die at the end."

Growing up, I would watch a movie on video and would go to the back of the VHS and locate the address for Universal Pictures or MGM or whatever. I'd write to the studios asking them if I could be in a movie. They never wrote me back.

Yeah, I know a lot of soldiers. I know soldiers who don't like to hear thank you for your service. And I know soldiers that do like to be told thank you for your service. The ones who don't like to be told are the ones who've been through serious sh*t. They don't care about feedback. They did their job. They did what they have to do. Sometimes the people that thank them are exactly the ones they don't want to be thanked by.

I fantasised about F. Scott Fitzgerald's 'The Great Gatsby' - I loved it, and then I read everything J. D. Salinger had to offer. Then I was turned on to Kerouac, and his spontaneous prose, his stream of consciousness way of writing. I admired him so much, and I romanticised so much about the '40s and '50s.
