Every project has its things to be overcome, but I didn't find that there was anything particularly impossible about what we were doing - it was all quite exciting.

The costumes, the light rigs and the effects are seamlessly joined. I'm kind of bummed that I don't get the experience that you get with just watching it cold. By the time we'd seen all the visuals put together, I'd sort of become used to that world. It's still pretty impressive.

The acting in Downton Abbey has been consistently excellent across the board.

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

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.

That was one of the things I hadn't really put together. Since the first movie and this movie, the rest of us have been living that revolution, largely engineered by people who were Tron fans. That's pretty deep, man.

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.
