Definitely at the Minskoff, not the Marquis, though I suppose that could change, but the reason The Minskoff was selected was because they felt its the theatre that the projections would work best in.
Supposedly, Crawford is not returning. Some site health concerns, some backstage difficulty, but I think its safe to say a Broadway run for him as Fosco is out of the question, which is a shame, because he was terrific in the part, and it would redeam him in NYC from DANCE OF THE VAMPS.
When I saw the show in London and talked to one of the creative staff, they said the producers secured the Marquis Theatre, as they said "The one in the Hotel"
While it would be nice for Mr. Crawford if he were to come to the U.S. with WIW, and I wish him well, I really do think that if Michael Ball comes over in the role the audience will be getting the better performance; he really was wonderful in the part.
I saw WIW last year with Michael Crawford in the role and while I'm not a huge fan of the show, I'd love to see what Michael Ball can do with the part. And if he's in it on this side of the pond, that's even better! Though I'm almost always up for a trip to London...
