You're used to having a camera in your face when you're playing a character - it's like having a mask on. But when you have to be you, you're so worried you'll make an idiot of yourself. Acting is a kind of escapism.
On my first TV job I didn't have a clue. They'd tell me to hit my mark and I had no idea what they meant. You just pick it up. And ultimately, all it's really about is pretending to be someone else.
I lack confidence, but I've been so lucky the way jobs have come to me, and I'm so grateful for them. I know how many brilliant actors there are out there who aren't getting the chances. While the work is there, I will grab it with both hands. It could all end tomorrow. You never know what's around the corner.
A lot of young girls who came to see me in 'Legally Blonde' have come to see 'Hedda,' and they hadn't heard of the play either, just like I was before I did it! If I can bring a younger generation to see an Ibsen play; that's just brilliant.
I always say to my Twitter followers to come to the stage door and meet me. What I love about being in the theatre, rather than filming, is that you meet your audience.
I swore on screen when I got the Olivier for 'Legally Blonde,' I was so surprised. Awards where the public vote mean a lot. I'm a big Twitter fan and like talking to people who support me.
I think the first album I bought was The Jackson Five, but the first CD I was given was 'Cotton-Eyed Joe,' the single! Bless my mum - don't know what she was thinkin'!
I've been so lucky with the people I've worked with, but I'm such a fan girl. When I moved to London at 16, I saw a man from a Dulux advert on the bus, and I asked for his autograph. I was so excited; you can imagine what I'm like now - I really need to control myself.
Kathy Burke has been a real inspiration. I think she's brilliant. I like the fact she doesn't care what she looks like on TV and just gets really into character. Obviously, she can do drama as well, but it's her comedy I love.
When I was 16, I played Tallulah in 'Bugsy Malone' at the Queen's Theatre. Me and five others shared a flat together in Blackheath. It was brilliant being 16 and living in London with my mates.
When I saw 'Legally Blonde' on Broadway, I rang my agent and said 'I want to be seen for this,' but the rest weren't big choices, really. 'Hedda Gabler' was a phone call offering it to me, and as I've said before quite embarrassingly, I didn't know the play, so I didn't sit there thinking 'I would now like to tackle Ibsen.'
