I like all films whether it's dark or light, love, hate, whatever it is, I enjoy it.

Oh God, you know what would be really good for me is a dog locater - it would save me the hours that I have to spend looking for my dog.

It's such a pleasant experience [being a part of the DC Universe], though very nerve-wracking to come on to someone else's set, essentially. They've been there for two years, so for me to sort of walk on and to be expected to jump into it, it's not always that easy. But they made it incredibly welcoming and hospitable, so I'm very grateful for that.

And to me, fame is not a positive thing. The idea of being famous is a lot better than the reality. It's fantastic when you go to premieres and people cheer you, but it's not real. And it's totally not my approach to get my name on a club door just because I can.

When you're playing a character for 10 years, it can challenge you less than it did at the beginning, so it was exciting to take on some new shoes. Especially with Erich Blunt, because being a tech wizard wasn't something I thought I would do after Harry Potter.

If someone tried to take the hierarchy thing too seriously - for example, being lovely to producers but moaning to runners about the tea - that would not be accepted on 'Harry Potter'; someone would pull you aside and have a word.

I'm not a big splurger of money, but my guilty pleasures do lie within BMWs. I get roped in.
