Sunset Contract's 'Mary' is a young, attractive, modern and down-to-earth woman with a sceptical attitude. Finding someone who fits this role is a daunting task.

The challenge of portraying 'Mary' is that she represents the audience's eyes and ears - as well as the protagonist's conscience. In a story so weird, this is extremely hard to do.

Anna Nightingale has all of the traits to rise to this challenge and win. Easily. I'm so happy to have found her.

And, on set, she was so flexible. If I wanted to make a change, she'd go with it. And add to it. Would think about it. Would try out anything. Would act on it.

I believe Anna created a memorable 'Mary'.
