The last UKtour which closed last year of Miss Saigon used a huge video projector screen to do the Helicopter scene.The sound was amazing and made it feel like it was right overyou but the video projection was not a hit with most audiences.
The shows was scaled down a bit to fit more theatres (the original set could only fit in 3 major touring houses one of which i worked in, and we were lucky enough to get that years ago) but the last tour wanted to visit more venues so was redesigned.
The scaling down of the show actually worked incredibly well, whilst the sets were still big they weren't as huge as the original and moved a lot faster making the show a lot more fluid.Audiences were adoring it but the moment the video screen came on with the Helicopter you could see people were annoyed.
Namo i love u but we get it already....you don't like Madonna
