I remember the “post-show” curtain Hello, Dolly! had was really fun. Are there any other notable examples of a curtain being used for just after the show?
As far as pre show curtains: The pre show scrim for The Music Man at The Goodman theatre last summer has probably been my favorite of any show in Chicago. The Lyric Opera also has had some interesting pre show scrims, such as the ones they used for West Side Story and Carousel. The worst pre show curtain/scrim that I have seen? Well, nothing beats The Bodyguard.
