The stage productions' 'Masquerade' is an actual Masquerade as opposed to the movie which is more of a grand ball than anything the movie scene destroyed the essence any Masquerade should have think about Halloween and the atmosphere that creates when people dress up and head out for trick-or-treating and other events. Even with help, it would not make sense in terms of the time frame given within the script especially if Christine, having the Angel of Music be in that room previous nights, knew he would appear and wanted everyone out within such a short time frame to be alone even if people questioned her.

The Phantom knowing and seeing this steps into action to bring Christine to his lair before she has the chance to reunite with Raoul a bit later. As for he dressing gown, or robe, Christine just arrived back to her dressing room and barely had time to change into an entirely new garment as would be suggested by the movie she tells Meg about her lovely Angel of Music and almost immediately Raoul comes in, invites her to dinner, and leaves. It is more historically accurate in terms of what would have been used and worn in the last nineteenth century, so the outfits were not created or sex appeal as was the movie version (because goodness forbid accuracy is actually present in a Hollywood production). The wishing dress is so pretty and the stage production just plain rules.

The movie is better in every way i have many problems with the stage show!
