I don't think I was particularly in need of superheroes. I never had any fascination with Superman or Spider-Man or a Batman kind of character. If it happened at all, it was imagined characters that I had invented. My dad was a role model for me. He was a fascinating man. There was intrigue and entertainment growing up with him. He gave me an edict that I still pursue: “Life should never be boring."

How serious can a movie about time-traveling robots be? You want it to be cool and fun.

But I learned that there's a certain character that can be built from embarrassing yourself endlessly. If you can sit happy with embarrassment, there's not much else that can really get to ya.

I'm English. Our dentistry is not world famous. But I made sure I got moldings of my old teeth beforehand because I miss them.

It helps so much being on location. It's like the difference between performing for the rectangle of the camera versus a world being created and then the camera finds things within that. There's a huge difference in that, because what it takes away is performance. You don't feel like performing. You're just kind of doing it. You're existing.

It's about pursuing it rather than waiting to see what comes along. That's partly because I found myself getting typecast, as everyone does unless they pursue roles that are very different from what they've done before.

I was born in Wales but I'm not Welsh - I'm English.
