I think either they don't care or they welcome the attention the movie will bring. I don't think they are banking on a long running hit, but rather a very hot ticket for people who wanna see one of the most famous and beloved shows done in a way no one has ever seen... and either see what people are raving about or hating on. I think the chance to see it another way, and live, is a strength for them selling tickets.. I don't think WSS being over-exposed due to the movie also coming out will hurt this particular production.
