“Actors’ Equity has contracts with the Broadway League and various producers that constrict what can be recorded; these also make it clear who owns the footage, and it’s not the actors. They can retweet or share something posted by the show or a news outlet, but they typically can’t just go on their own for self-promotion purposes. In recent years, because of the growing importance of social media, actors have been grumbling that they need footage rights.”
