It's as simple as this: If you've got a play called The Heiress, it's absolutely obligatory that whoever assumes the eponymous role is utterly persuasive. Unfortunately, that's not the case at the Walter Kerr.
I sometimes wonder why the majority of them do it. But I thank them all because without someone to produce the theater there would be no theater. This fall/winter the producers presenting work run the gamut from newbies to vets.
