Regarding the cast, from the NYT's recent article on Jeffrey Seller:
Last fall, it was reported that members of the cast asked Seller for a share of the gross, though they are not owed that by contract. “They are the ones bringing this show to life,” he told me. “It was a powerful argument they made; it was gut-wrenching for me, and I took it seriously.” (He would not give specifics but said that he had reached an agreement and that the matter was resolved, at least for now.) Most cast members are working on 52-week contracts, which began July 13, the first day of Broadway previews, and those who intend to stay will soon be negotiating new deals.
