Sharpe is my favorite role of all that I've played. He's a very complex character. He knows that he's a good soldier, but he will always have to fight the prejudice of aristocratic officers because of his rough working-class upbringing. On the battlefield, he's full of confidence - but off it, he is unsure, a bit shy and ill at ease.
In theatre, once you've got the character and you've got things together, you can relax into it. Film has a different feel - you don't get that through line of not stopping. Theatre is like a snowball gathering momentum and getting bigger, whereas in film, it's a bit stop and start - but you do tend to adjust to that quite easily.
