It's literally theactorstaking a bow. Plus, those who who run theofficial social media sites of each show have 1000%posted, say, the opening night curtain call as well as closing. If it were illegal to film curtain call, I can't imagine the OFFICIAL social media sites would be doing this."
The curtain call is certainly part of the show. It is part of the direction, you're still looking at the copyrighted designs, and, especially with musicals, there is still copyrighted music being played.
As for the official sites taking video, that's exactly why it's allowed, because they are OFFICIAL. They have obtained the rights and followed the rules for filming laid out by the various union contracts.
