You know, boy versus girl. But she's a tough warrior, so I almost treated it like unisex. But it makes a difference how tall the actors are, because I needed to know that if Olivia Wilde sits in a car that the director, Joe Kosinski can still get the angle he wants, as opposed to maybe in another vehicle than Jeff Bridges has to sit in. So that was fascinating. Because in a real car you change everything and adjust it. But here you have one shot.

Sam's light-cycle, the car, and the jets are new of course, and other stuff. The new ones are sleeker and so contemporary, that if you could put them in a car design show they would hold up.

The downside is, if somebody doesn't like it, then it's like "oh my god, ok its really your fault."

At any given day you have to be ready with everything. It can be that the director says "this one's done and I need a new one." And you're like, "oh my god! I only have two months, no way!" So your design approach is completely different. You develop, let's say six things at the same time, and try to be ready everyday to give it away.

It [making tron: Legacy movie] was everything. I got pulled into a different country, in a different language, and a different society. In a movie, it's a completely different feel. In car design you know you have one year, and you have to go step by step. This is an organized catastrophe.

The funny thing is that Sydney, who worked on the first film [Tron], developed a bike that had an exposed rider, but they couldn't do it because the computers weren't fast enough, so they gave it a roof, which became the iconic one. Ironically what we do now is basically what they envisioned in the first one but couldn't do technically. I mean this a full on homage in every aspect.

It's still the classic thing to get nice lines, but knowing that your computer model, on your little machine, is on the screen, is priceless. And that doesn't happen too often I don't think.
