I started singing for The Phantom in January, and we started filming in October and I sang all the way through to the next June. In fact, I was singing for about two months before I even knew I had the role.

To me, all those jobs I did [roles] have been amazing experiences for one reason or another. I got paid and I learned something. I think that's what helped me carry on because I've never really given out that energy of, "oh, I've lost my chance" or missed it in some way.

I have a level of fear going into every project, and that's what keeps me going.

I sang in a rock band when I was training as a lawyer. You know, not professional, we just did it for fun. We just did gigs all over Edinburgh and some in Glasgow and some at festivals.

In actual fact, I wanted to be an actor, but I was a lawyer, and I was a week away from qualifying and was fired. And that's the day I made an announcement: "Hey, for seven years, you thought I was going to be a lawyer. Well, I'm not. I've just lost my job, and I'm packing my bags and moving to London tomorrow to be an actor."

I love to do films of all shapes and sizes and feelings and genres. So for me to go from Tomb Raider straight into Dear Frankie, there's nothing that excites me more than to keep mixing it up.

I went from somebody who didn't sing to somebody who didn't speak.
