27 March: Mousetrap’s little known records

First Published 23 April 2008, Last Updated 23 April 2008

Many people know that at 55 years, The Mousetrap holds the record as the longest running show in theatre history. Less know of the records held by its long-serving cast members.

In 1994, the world’s longest serving understudy, Nancy Seabrooke, retired from her position at The Mousetrap, where she had been understudying the role of Mrs Boyle for a total of 15 years.

Seabrooke, an actress from Middlesex, joined the show in 1979 and, in 6,240 performances of the long-running whodunit, played Mrs Boyle only 72 times. She died in 2003.

Seabrooke is not the only record-breaking actor to appear in Agatha Christie’s most enduring play. Actor David Raven made it into the Guinness Book of Records as “Most Durable Actor” for his 4,575 performances as Major Metcalf.

Spare a thought, though, for the show’s costume department which, during the thriller’s record-breaking run, has ironed over 100 miles of shirts.

We now sell our famous TKTS Booth discounts online here at Official London Theatre.

We are now cancelling all performances up until and including 31 May 2020 to help us process existing bookings whilst we wait for further clarity from the government in terms of when we will be able to reopen.

We are so sorry that in these testing and difficult times you are not able to enjoy the show you have booked for and hope the following helps clarify next steps in respect of your tickets .

There is nothing that you need to do if your performance has been cancelled, but we do ask for your patience.

If you have booked directly with the theatre or show website for an affected performance, please be assured that they will contact you directly to arrange an exchange for a later date, a credit note/voucher or a refund. If you have booked via a ticket agent they will also be in contact with you directly.

We are processing in strict date order of performance, so you are likely to be contacted after the date you were due to go to the theatre. However, we want to reassure you that you will be contacted, and your order will be processed, but please do bear with us.

We’d like to thank everyone who has been patient and kind in dealing with their ticket providers so far and we are sorry that we cannot process your order as quickly as we would like.

Please do not contact your credit card company as that will slow the process down and put an additional burden on our box office and ticket agent teams.

In order for us to serve our audiences the best we can, please do not get in touch with your point of sale if you have booked for performances after 31 May. Please be reassured that if we have to cancel future performances you will be directly contacted by your theatre or ticket provider. Our producers continue to plan for all eventualities dependent on the individual needs of their shows and we will provide further updates on specific shows as and when they become available.

We look forward to welcoming you back into our theatres as soon as we are allowed to resume performances. In the meantime stay safe and healthy.

While theatres are currently closed, various venues and productions are making announcements for their individual shows, including cancellations and rescheduled performances. Please check with the individual shows for details.
