I'm fascinated by artificial intelligence.

Wormholes don't exist because the only way they would exist is if they were seeded with exotic material created by an intelligence far beyond our own. Something would have to make one.

My earliest memories are making little Super 8 films - or watching my brother make stop-motion space spectaculars.

Look at anyone's bookcase at home, no matter how modest, and you're going to find a book that contains wisdom or ideas or a language that's at least a thousand years old. And the idea that humans have created a mechanism to time travel, to hurl ideas into the future, it sort of bookends. Books are a time machine.

I remain deeply interested in the transformation of the American healthcare system to improve quality and contain costs.

We are going to transform Britain's rail system from the worst in the world to the best. If you can do a few things like that, when the body gives out, you can say you've lived a good life.

I love the ability to transform because that, for me, is a liberation.

I recognize my physical limitations, but I am an actor who is able to transform himself into someone else.
