I've never done a superhero movie. It's very nice to you as an actor in several worlds to go and to experiment.

As a child, I always liked dressing up and getting into character, and actors are lucky in being able to retain that playfulness, though we do seem to find it hard to grow up.

Now younger actresses will have a confidence in those discussions with their agents and be able to say, "Can we make sure that I'm being paid the right amount for the work that I'm doing?"

Going to auditions is always so nerve-wracking. I don't think they ever get any easier.

I've been very lucky. Directors I've worked with have been very amenable to changes.

I think Nelly [Ternan] actually has something very conservative about her, and she's very judgmental of (this other character's) situation, and can see that's about to happen to herself. So she judges it even more harshly [because] it's what she fears becoming.

The key is working with great directors. A film is so many different people and all their talents, but particularly the directors, because of the idiosyncrasies of that person.
