I think becoming an actor because it's a ridiculously insecure profession to go into. I feel very comfortable but very lucky. I think any time that you imagine that it's plain sailing for hereon in, then you're kidding yourself.

The little song and dance number at the end - that's me, my voice, howling out. It was a new experience for me. I've never sung before and I've certainly never sung on screen. I think I sung on stage when I was 13 and for some reason nobody's asked me to try it again since.

In reality, for me every role is completely different.

You can still have chemistry on screen without getting on with the person. But it just makes your job a lot easier if you don't have to gird your loins, if that's not quite the right phrase, every time you're going to do a scene with that person.

I think I can lead a pretty anonymous life, yeah.

In my experience it's not essential to get on with the person that you're acting opposite.

In real life, I try to be honest but not overshare. There are people that turn every conversation into a therapy session and you want to start charging them.
