I work in theatre in London and the reason it does so well here is due to tourism, plain and simple, and that’s due to its iconic status as part of London’s history. If you glance at the London trip advisor forum, the one show that’s mentioned absolutely constantly is the bloody Mousetrap. People who’ve never been to the theatre go see it because it’s just kind of on the standard Tourist Attractions of London List: Buckingham Palace, Tower of London, Big Ben (which is really the bell), Tower Bridge (which half of them think is named London Bridge), High Tea (which is really Afternoon Tea), fish and chips in a pub (sacrilege!), and the Mousetrap.
Another big part of the appeal is the theatre itself, which is living history and has such a big collection of paintings and old documents and things on display it’s essentially a museum as well.
I actually went to see the Mousetrap this year and I liked it a lot in a faintly soporific way, but I have a weird penchant for dusty old murder mysteries. I enjoyed the tradition and ritual of it. But I honestly don’t know one person in the theatre industry who’s ever seen it. It’s almost like not part of the industry at all, but parallel to it. I don’t mean that in a snobbish way, just that it’s considered a museum piece/tourist attraction, not a piece of theatre.
The news that it’s going to New York has boggled quite a lot of minds, and I can’t imagine it’ll do well unless they cast and market it very cleverly. I don’t know what kind of audience there is in NY for London history, because the whole reason it’s successful in London won’t be there.
(Re the blind item. Of the three female parts, two are in their 20s. It’s a key plot point that one of them is young, and the other - a newlywed - could maybe be played a little older but is very young in personality. I don’t think the BI can be about this show.)
