What to Watch For

• Look out for the wooden sign at the entrance to St. Martin's Theatre — it tallies up the number of performances to date and will let you know which performance of this record-breaking show you are attending.
• The Mousetrap play was written as a gift for Queen Mary’s 80th birthday in 1947. Agatha Christie then gave her grandson, Mathew Pritchard, the rights to the play for his ninth birthday.
• The clock above the fireplace in the main hall is the same clock that was used on opening night in 1952.
• Former cast members have given record-breaking contributions. One of the original cast members, David Guyler, provided the prerecorded voice of the newsreader in the shop.
• David Raven is in the Guiness Book of Records as the “Most Durable Actor” having performed 4,575 performances as Major Metcalf. The late Nancy Seabrooke also holds a record for an impressive 15 years as an understudy in The Mousetrap.
