No actor can play a villain if they don't sympathise with him or her - otherwise the character just becomes a two-dimensional caricature.

It's not an understatement to say that I owe everything as an actor to 'Merlin.' It was pretty much my first job, and I didn't know what I was doing for many years on it. It wasn't until the third and fourth series - the fourth series especially - that I really found my feet with the character, and as an actress.

I get sent lots of jewellery by fans, and that's absolutely lovely.
