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 actually signed on to do 'On the Road' before we started on 'Tron,' but we were in flux for a while, just sort of playing the waiting game, trying to get the right budget and the right cast.

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.

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 had never heard much about Nashville before coming out here, and that's why it's so surprising, because I'm the biggest enthusiast on the city of Nashville now. I'm looking for a place out here to live.

It was close to like a 67- or 70-day shoot for 'Tron' on stage, in the suit. You can't even sit down during the day because of all the cables that divide the foam rubber and all the electrical circuits. We had these stools that were tall with a bicycle seat on them and you're just looking at a blue screen all day.

A great amount of good is always evened out by a great amount of bad. I find it's best to acknowledge that weird balance.
