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.

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 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.

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.

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.

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.
