What drew you to the play?
Bonnie: Firstly that it was written by Peter Ustinov, who has always been a fascinating figure within the arts for me - he was a master of so many forms. Although written in 1950's, the themes are very relevant for an audience today.

Did you enjoy rehearsals?
Bonnie: My first few days I felt like I was speaking a foreign language, whilst trying to stay afloat in the middle of the ocean. But I am loving every moment of the challenge, every day I feel like I am evolving in some way. The rest of the cast have been fascinating to work with.

Do you identify with your character at all?
Bonnie: Not at all and that's why I love playing her.

What made you want to make your stage debut?
Bonnie: It has always been an art form that I have wanted to explore, and I feel that now was the right time professionally and personally to do it.

What did you learn from your Harry Potter experiences?
Bonnie: Everything. It was the foundation for my career.

Would you like to do more stage acting after The Moment of Truth?
Bonnie: Yes.

What's next?
Bonnie: After I finish the play I am going to have a short break in Italy. I then get back to London for the release of The Sea - a film I shot at the end of last year. I then have a few projects in the pipeline.
