I've never done a lead role in a film this big [like Doctor Strange], in a franchise this big. One of the reasons was, I wanted to know what the toy box was like. And it's just insane, the amount of facility that everyone gets, but the amount of artistry and craft that's brought to every aspect of filmmaking. I mean, you go to your first costume fitting and it's one of thirty. It's a myriad, but it's for a reason. There are so many incredible costumes in this.

Talking about class terrifies me. There is no way of winning.

I wanted to take the audience on a journey where that transition was funny and awkward. It's the same cynicism that [Strange] has.

There's a huge raft of roles that actors in our culture perform, and you can see any one of about three Hamlets in a year. It's not something to be completely daunted by.

It was great. I got to hang out with him [Martin Freeman as Bilbo Baggins], and I kept a straight face for a bit and then I started giggling because I know Martin, I don't know Bilbo. For Martin to be sitting there playing Bilbo is amazing. He's going to be amazing, he's going to be fantastic in this film.

When auditioning, I try to imagine that I'm the only person that they [directors] are seeing that day because it can be overwhelming, in the same sense that it could be overwhelming if you try to fulfil everyone's expectations rather than the people closest to you in the creative process, be it your director, or fellow actors and the writers. So, that's kind of it - I try to trick myself into believing that no one has ever gone there before.

Sometimes being away, on location, I feel like I'm away for much of my own life. I want to be better at staying connected.
