When you come across someone colorful and vibrant maybe in the present it isn't so interesting, but, in the past, it sheds a wonderful light onto living 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.

It’s funny, though, speaking of fathers and sons, because me and John Goodman played father and son, like, five or six years ago in the film Death Sentence [2007], and I got back with him again in Inside Llewyn Davis.

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 had to jump on the tractor and do my chores. I would have just killed to be in town, to be able to Rollerblade hand-in-hand with somebody I had a crush on. I just wanted to get off the farm, to find my outlet.

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.
