Myth: A big Broadway hit will help all of Broadway.
Fact: A mega hit on Broadway sucks all the oxygen out of the room, leaving other shows to struggle for leftover crumbs. This year is a great example. The most mega-y hit in years, Hamilton, has helped Broadway as a whole to reach yet another new high in revenue. Just beneath the surface of these numbers shows a different story. A first ever reduction in average ticket price and a reported 27% drop in revenue for straight plays. Those high revenues are flowing to the perennial Disney shows, Wicked, Book of Mormon, and now Hamilton. Early casualties this season include, American Psycho, Tuck Everlasting, Disaster, with others to follow shortly. High profile plays like Hughie and Misery flamed out and failed to recoup.
Myth: Whistling in a theater is bad luck.
Fact: This may or may not be true, but just don't do it!
