That's the main thing that attracts me - characters who have big journeys. I like playing those people.

I'm taking probably the biggest risk of my career in playing the part in Filth. If you stop taking risks, then you get bored, or you just keep playing the same part, over and over again. Eventually audiences get bored of that, as well.

I also really liked playing Mr. Tumnus in 'Narnia'. I got to play my favorite character in children's literature, which I loved. You don't get the chance to do that in other jobs.

I kind of embarked on a fruitless search to find information about my character, Frederick Aiken. And it was fruitless, unfortunately, because there's so little about him.

In a love scene that's really advantageous because you don't have that horrible moment of: "We don't really know what we're supposed to be doing, we just know we're supposed to be snogging and then shagging." Then the director shouts "action" and it's like: "Should I feel her boobs? I don't want to feel her boobs!"

I always have a beard between jobs. I just let it grow until they pay me to shave it. People are quite surprised it's ginger. Sometimes they ask me if dye my hair and I always say 'Wow, no!' I'm 'trans-ginger.'

The script is the most important thing for me. I'm advised that other things are important too, and they are. The director that you'll be working with is hugely important, and the cast that are with you is really important as well. But, for me, the thing that gets my heart excited and really makes me invested in something or not is just the quality of the script.
