I think I've had very knee-jerk emotional reactions to things, and sometimes I've said things without thinking. Being overly emotional clouded my judgment.

The biggest lesson Stephen Strange learns in this film is it's not all about him.

I have pitfalls. I have emotional responses to things that are really not about me. They're about other people.

I would love to just have the work do the talking. We're in positions where people ask us questions; they want to know about more than just the work. And it can go into areas where I've completely shot my mouth off, whether it's too much about my private life or being too opinionated about things in the world. I think the better thing to do - I've learned this from people far wiser than me - is to do very good, quiet work behind closed doors.

I'm aware of [Doctor Strange] place within the comic pantheon of it all, the Marvelverse, but I don't email saying, "When are we doing next film?" I'm excited to see.

I'm always keen to use my body in my work, so I'm looking forward to the motion capture for Smaug. Both Gollum and King Kong were primates, whereas I'm playing a serpent, so it'll be interesting - I'll have to tie my legs together, possibly, or else they'll be kind of splayed out to the side as a reptile's should be.

The first time we did cavalry charge I was so breathless with excitement I nearly fell off the horse. I actually saw stars in front of my eyes and thought I was going to faint. The second time I had a bit more control but was still giddy with excitement. And the third time I was an emotional wreck. I had to really try hard not to cry.
