I've seen two big ones, the Worth/Walken (Kennedy Center, DC) that worked, the Bacall (London) that didn't work at all, Bacall shockingly at sea with a role that was eerily a perfect fit The second act is just another play, and as we leave the Princess and move into the lurid dealings of this humid little Southern town, the focus becomes diffused, and even if well cast, it feels like water treading. (Heavenly's plight fails to engage us.) Chance is sort of a Brick if he'd led another life, and devilishly hard to nail. Walken, as noted, was unknown and kind of brilliant. I would've killed to see the Cromer/Lane. Moving the Princess away from the grande diva and casting a luminous actor seems shrewd. It's an unapolgetically operatic play that would benefit from less opera, more human scale.
