[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.

I understand from those who adore him, he [Julian Assange] has a great sense of humor which rarely gets an airing because he's dealing with such serious issues.

One of the fears of having too much work is not having time to observe. And once you get recognised, there is nowhere for you to look any more. You can't sit on a night bus and watch it all happen.

I don't want to miss things.

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.

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.

All the backstories are there but not talked about.
