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.

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.

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

I would want to keep that in a little glass sphere, perhaps in the corner of my living room, lit up. But, I think that's an extremely expensive rig. The costumes were crazy expensive, beyond anything they could afford to give you, to take away. They're going to be in a museum of some kind, on display until they get the go for Tron: Legacy 2. It would have been awesome to keep, though. I don't think there was anything that they could afford to let go. I probably would have been arrested.

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.

X-Files wasnt a big show in England.
