I am a little in awe of Jeff Bridges. He's an actor I have admired for many years, and so I didn't know who I was going to get, in the sense that I didn't know what he was going to be like. And so I was pleasantly surprised that he is this kind of laid-back guy.

Working in 3D I didn't experience much of a difference, except that the cameras are very big so they can't be moved around with as much ease. It was more like, when you've seen photos of cameras from the 1930s being moved around with these huge cranes. So there was something quite sort of old-fashioned about it almost.

I was surprised by how much of it I was in [Tron: Legacy]. I thought the character was just going to register as a smaller figure because most of what I did was with a body double, and then I would do the stand-in with Jeff [Bridges] and he would be just wearing his regular clothes.

Working with Joe [Kosinski], definitely. I loved working with Joe. For a guy who doesn't really come from the fiction world - he comes from advertising and architecture - he's extremely easy-going and very calm. He's extremely detailed, but a very generous and fun director to work with. He really encouraged me to find the fun in the part and to have fun with it.

As movies and TV projects come up, they go out to the agents and we just go out and audition for them.

Working with CGI is more like doing theater where your sort of imagining things. I didn't experience it as restrictive.

The problem with trying to make a film good and have it work for an audience is the problem of trying to tell a story well. The shape or the color of it doesn't matter.
