It's obvious that if you're going to play a character you need to amass information about that person and about their environment or their era that they're in and use as little or as much as necessary

I take my hat off to the ladies. The amount of grooming-plucking and shaving and all the other things men never have to do. I went down and spent time with transvestites in London in the clubs and all that. Got an insight to that world, and it's a mad world, but they are very warm and very open people. It was a great experience.

I don't care if people perceive me as always selling out because I'm doing a studio picture. For me, the whole thing is you should be diverse in your choices; that's the beauty of being an actor, you should be able to do that.

And, for any performer, to be able to go deep into character is fantastic. In film you only get to do that if you're the leading character. But in television you get 18 hours to really test the audience and take them to the edge of how far they will go with this character. I can step over this line and I love that.

I'm Irish and very proud of being Irish, but as an actor, your extraction should be secondary, really. You should be able to embody whatever character it is, wherever the character comes from. That's always been important, for me. I'm an actor who's Irish, not an Irish actor.

I think for me with theater, I need to take a break and then fall in love with it again. And then go do it again.

I really feel actors should try and do as much diverse work as possible to try and keep it interesting.
