I always devise a background so that it makes what your character goes through logical and keeps up the continuity.

It took me a long time to make that leap to being a grown-up and responsible adult because I carried on being a child actor into my late twenties. It's OK to be precocious when you're young, but when you're a man of about 27 or 28 and playing a 17-year-old in a TV show, it kind of prolongs your childhood.

I love walking along Leith's waterfront and wandering around some of New Town's beautiful streets and squares, with their gorgeous Georgian architecture.

My first trip abroad was to do a TV version of 'Les Miserables' in France with Anthony Perkins. There I was at 12 acting with the guy from 'Psycho.' My parents were teachers, and it was hard for them to relate to that world.

It was very amazing. Every week that goes by, he keeps amazing me more and more.

What keeps me up is always raising the bar, and what makes my team happiest and also most worrisome is I'm always asking for more.
