First of all, this must be the biggest backstage of a theatre in the universe and the loudest that isn't heard in the auditorium. The music arrangements are very good and the actors are enjoying themselves, which is what makes the film a lot of fun. It's a spoof of how it is in the theatre. The stage manager doesn't leave it's place during the performance, no one is that loud during performance, but a lot of stuff happens backstage during performance. The orchestra doesn't stop playing when things go wrong, The entire production makes sure that the audience doesn't realise the backstage fights, problems and faults that happens in front of them. But, again, it's a fun film.
