 FACT: Near the beginning of the film, there is a shot of the Belasco  Theatre in New York, where Sidalees play is about to start  performances. The Main marquee and windows on the theatre display  the marquee for her play. However, one of the marquees over the  entrance has a general marquee that reads "See a Broadway show just  for the fun of it!". The Shubert Organization (which owns the  theatre) only uses these generic marquees in a theatre that is  currently empty and no upcoming show is booked into it. This marquee  would never appear on a theatre that is in previews/has a show about  to open.
