THE WOLVES, for sure. Even if it hadn't beaten Harry Potter this year (although it was a Pulitzer finalist, so they certainly would've had a chance), it still would be great for a Broadway audience to see this.
If they can mount Ivo's VIEW FROM THE BRIDGE, I think they could stage THE WOLVES very similarly in a proscenium space.
Unfortunately, now that regional productions are popping up, I don't think it'll make its way to Broadway. Even though it sold out at Lincoln Center as soon as it went on sale.
Also, my #1 show I'd give anything to see again is LET THE RIGHT ONE IN, which I'm praying they'll let Tiffany remount after the success of Harry Potter. It's one of my favorite things I've ever, ever seen. They did something similar in London where the transfered over The Glass Menagerie last Spring, so I'm hoping the same can happen here. I think it could kill in a limited run in a medium sized house.
