Behind the scenes at The Mousetrap | Dressing Room Confessions

For more behind-the-scenes videos from London theatres, go to http://www.timeout.com/behindthescenes The legendary Agatha Christie, playwright behind 'The Mousetrap', thought that her murder mystery would only run for a few months. How wrong she was. After making its West End debut in 1952, the play celebrated its 250,000th performance earlier this year, and is still going strong. To celebrate 'The Mousetrap's Olivier Awards Audience Award nomination, we speak to two ladies who have played the piece's Miss Caswell in different decades: Denise Silvey, who last took the stage in the play's forty-third and fiftieth years, and the current Miss Caswell, Natasha Rickman (who's mother, Miranda Bell, also played the part in the thirty-third year of the production). They give Time Out an insight into 'The Mousetrap's timeless appeal. Camerawork and editing by Vin Shahrestani Planning and direction by Oliver Robinson
