Olivia: Every now and then I think I should write something, and I'd love to get a crack at doing my own stuff, but I can't write so that's no use!
Olivia: I always imagined I'd be playing Lady Macbeth and Medea and things, but it turned out I wasn't very good at that. So luckily I got work doing comedy acting, actoring, and I love it.
Olivia: This may sound mad, but you sort of assume that no one's going to watch what you do. You go on set, have a lovely time, and then you forget anyone's going to see it. So it's always a bit of a shock to be recognised. I get terribly embarrassed.
Olivia: Thankfully, I'm still at the level where most people don't know who I am. I prefer it like that. I'm basically a slipper-wearing, parka-wearing, slightly spotty lady, who likes to wander around Peckham with her pushchair.
