vampire musical said: "Non-verbal shows are thriving because they are non-union. It's hard to turn a profit with under 499 seats unless it's a one person show that has somewhat of a name actor (Come Sleep Walk With Me, etc.), a former Broadway show (Avenue Q), or non-union (Sleep No More, Fuerza, Blue Man, Stomp). "
right on all points. Two further points: First, the economics of doing a legitimate theatre piece is actually more acute in the 200-499 range than below it. And second, it does not have to be thus. The folks at the Barrow Street have solved the riddle, but no one else seems capable of learning from them. The lesson I think we need to learn is that the real estate is not the culprit; it is a symptom. We keep hearing these choruses of dismay that building are being put to other uses but we seem oblivious to the fact that these landlords are not turning down great theatre: it is just that no one is producing it. When you consider that so many Broadway shows are unmitigated flops, it is not surprising that any halfway decent show is going to take its chances on Broadway rather than at the larger end of the off-B market. E.g., The Humans.
