A woman who knows that she doesn't have to get all decked out to look good is sexy. A woman who can make you feel smart with her conversation skills is also sexy. I believe the sense of humor is important.

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.

There's a huge amount of footage of Julian [ Assange] online, but he's usually in presentation or defending mode, talking about his cause, or the revelations which Wikileaks have brought about. There's none of Assange relaxing or in private mode. There's none of the personality I tried to give him behind closed doors [in The Fifth Estate ].

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 am also full of admiration for Chelsea Manning [formerly PFC Bradley Manning]. Regardless of which side of the argument you're on, he stood up for something he felt wasn't right. That was an extraordinarily brave thing to do, and I think he was unfairly punished for it. It's a really big deal what he did, and he did it for the betterment of all us, including the soldiers on the ground, as well as the civilians caught up in those conflicts.

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.

Do awards change careers? Well, I haven't heard of many stories where that's the case. It's a fun excuse to meet colleagues and celebrate people who've done well that year in certain people's eyes, and it's nothing more than that.
