It’s funny now, trying to socialise with people. There’s this cautiousness about people which I just find really weird.

I haven't really decided to be an actor yet! I started doing plays when I was about 15 or 16. I only did it because my dad saw a bunch of pretty girls in a restaurant and he asked them where they came from and they said drama group. He said, 'Son, that is where you need to go.

The first period of getting famous was incredibly strange to me and really fun at the beginning because you didn't realise the consequences of anything. You could say or do whatever you wanted and it just didn't matter.

Whenever I have to do anything fan-related there's always a whole bunch of people. My brain kind of shuts down when there are loads of people screaming at me. I'm not thinking at all so I can't really remember what's happened immediately afterwards.

I think so much of a director's job is just to convince you that what you're doing is worthwhile. "Yes, this does mean something, we're not just messing around." Even though at the end of the day it's a film. But at the time it's something else. I don't feel like I'm making a film, I'm confronting things in myself. I don't know what it is. So if someone is enthusiastic enough to convince you that it's important it's kind of magical.

Every cent that goes to research is changing the lives of patients and their families right now.

People ask me if I'm afraid of getting typecast, but you can't be afraid of that. It's really not up to you. I'm getting other parts that aren't vampires.
