Isn't this basically the same premise as Noises Off...?
No, but it is exactly the same premise as The Farndale Avenue Housing Estate Townswomen's Guild Dramatic Society Murder Mystery. It is on a larger set and it is indeed fun, but it's really sad that this new franchise so blatantly rips off its predecessor (established over 30 years ago) which had already established a franchise of its own, but because they were meant to be small productions, they will likely be obliterated from memory and those not familiar with them will probably mistakenly claim the Farndale shows are the plagiarists. The author of the Farndale shows was already preparing to mount their Peter Pan production when he learned that Mischief Theatre announced the opening of their own Peter Pan Goes Wrong version with a theatre in place (and subsequent national tour). I was already a fan of the Farndale shows and had seen three or four of them, but I didn't realize until I saw Goes Wrong in London that not only was the genre of choice the same as the Farndale inaugural show, but the basis of so many bits and gags were lifted directly from the Farndale shows.
