I imagine that if a Broadway transfer is being bandied about, it wouldn't happen until next fall at the earliest. Denise Gough is doing ANGELS IN AMERICA this spring.
As for Brantley/Green: Maybe BB felt such antipathy toward the play that he didn't feel the desire to review it again, and passed it down the line. I certainly wouldn't be jumping at the chance to sit through a play I didn't like for a second time.
