It's always hard but the reality is, especially in my case, that every time I go to work I have to do it so it's become part of the job. It's an extra challenge but it's also quite often another extra tool that you have to really think consciously about getting into the character. So while it does require more work, it's maybe even an advantage to a degree because it forces you to switch, to consciously have to jump into and out of the character.

I'd say I'm the opposite of someone that has the urge to stand in front of strangers and make them laugh, but the idea of getting up and telling a story and people finding it amusing always appealed to me.

I didn't study Greek mythology in school and I wish I had.

The more I love the character, the harder it is to get it wrong. I have to get to a point that I can speak for them.

I'm a bit of a romantic.

But it's healthy - whatever you can do to keep you fresh and awake. Acting's such a ridiculous job and sometimes you need to look at it like that to get a sort of degree of freshness.

It's got to be a challenge but at the same time you have to feel as though you can play them - it's really dangerous to want to be a part of something just because you think it's going to be great. I've been sent plenty of scripts where I've known that it's going to be a great film and a successful one, but I just couldn't convince myself that I was the right person for the part. So, I think you have to be careful with that.
