[Scott Derrickson] is terrific, really sharp on the details, and he's not afraid to go to dark places.

I know that might sound perverse because I played Julian Assange but, honestly, I don't think it would be fair for me to judge the man.

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.

What's not to look forward to? It's like all the actors in all of the films. It's difficult to get Martin Freeman and I in a room together.
