I didn't have any desire to be an actor until right before I did it.

I worked in an insurance office for six years, and it was there that I just woke up one day and realised there was something massively lacking in my life, and a non-contributory pension and a subsidised canteen could not fill it.

I was 18 and making 150 quid a week, which was a lot of money to me. Then there was a bad winter and I got paid off. Then my firm, JW Henderson of Bowling Green Street, Leith, went bust. If they hadn't folded, I'd probably still be scaffolding and loving it.

Acting is rare. You can be rehearsing Ibsen with Sir Richard Eyre and suddenly he has to take a call on his mobile telling him his friend Arthur Miller has died. Or you can come back from a job on the Isle of Man to be told by your agent you're going straight out to South Africa on another shoot. There's not even any time to wash your pants.
