Glenda's Lear also strikes me as a production best suited for a limited run at BAM. The production was so bizarre, I don't see it doing well on Broadway, even with her name attached. Similarly, I think The Kid Stays in the Picture would be more suited to one of the big off-Bway non-profits, like the Public, the Signature, or St. Ann's.
I don't see Travesties transferring, but Staunton's Gypsy could definitely do well, as well as the Ferryman. Richard III might be problem with Redgrave's age, but I guess Fiennes could always do it without her. Still, I doubt it will come over, given that it's been almost a year with no word, and it didn't even transfer to the West End (I know, I know, that didn't stop American Psycho, but still)
