My massive motivation in life is to make parents proud. But even that has to stop at a point.

[Doctor Strange] is still quite cocky by the end of the film. No, I'd say the major curve for him is that he learns that it's not all about him, that there's a greater good. But what he thinks he was doing as a neurosurgeon, that was good because it benefitted people's health was really just a furtherment of his attempts to control death and control his own fate and other people's, but that's still driven by the ego.

[Role of Dr.Strange] gives me an excuse as an actor to be learning with my character, which is something you can do authentically - I'm not a martial arts expert, I'm certainly no sorcerer, so all these things, the movement of the body, the physicality, the changes he goes through mentally and physically, obviously we're not shooting in sequence, but it's a great part.

What makes a good animated movie is being able to balance adult and knowing in-jokes and also just out and out funny things that make all people laugh. The idea that it's actually something that will appeal to a family, that's the trick.

I'm a Prince of Wales Trust ambassador, so I'm all about giving youth an education, a voice and a chance to not take the wrong road.

Being on set is quite difficult, because it's so big and you've got to try and relax, which isn't easy when you know you're in a massive film. I was terrified for quite a long time.

I'm always playing characters with intellects profoundly superior to mine. That's great fun, even though it's as much a fantasy for me as for the people watching me.
