I was very aware of the legend, from such an early age. Being a Brit, you are so aware of King Arthur, Camelot, Guinevere and Morgan, the witch. Merlin is this mad magician who's cloaked in mystery. It has that mystery about it. And, it's a lead role for a woman that's strong and has a real journey to take.

I don't know what it is about me, but I don't think of myself as sexy; I never have.

I suppose I am one of those lucky people who eats what they like and doesn't gain too much weight.

But, as an actress, you don't want to run into these scenes, willy-nilly. The couple that I did do were important for the character and essential to the plot, to show what was actually going on between each character. It is great to be able to have that, and to be able to say certain things and have certain passions.

Guinevere has been done quite a few times, especially as a mature young woman, who either is the damsel in distress or the warrior, strong-willed woman. Chris wanted a variety of things in this Guinevere. He predominately wanted her to be real and natural, and make mistakes and be passionate, and be the feisty young girl, but then also completely naive, innocent and ignorant, at the same time.

I love jewellery, but it's something I go through stages with. I have my go-to pieces that I will bring out and wear for weeks at a time.

Always take earplugs and an eye mask. It doesn't matter where you are. Even if you're in the best hotel, if there's road works outside, then you're screwed. So I take earplugs and an eye mask with me wherever I go.
