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.

And sometimes it's fun to be the guy who just really enjoys it, like the guy I'm playing now on The Cape. He's more that. He's much more flashy and debonaire and devil may care-ish. He just loves doing bad in the world. That's real fun to do.

I also thought the music was a huge contribution, in terms of creating the scale of that. And, I was impressed with just how natural and fluid the world looks. The world is so artificial and it requires so much work to make all the different pieces add up together, but when it comes together, it just looks effortless. It's amazing.

Evil is a broad church. There are so many different ways to be evil. Sometimes it's fun to be the guy who doesn't know that he's bad, like the character I played in True Blood. He was pretty angsty about it, but he thought he was doing the right thing.

With my guy, every now and then, he puts on a mask and does that, but he isn't that. Most of the time that we see him, he isn't that. Most of the time that we see him, he's fun to hang around with. I think that's unusual, to that extent.

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.

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.
