Tennessee Williams’s The Night of the Iguana is often considered his last great play, but the 1961 milestone was created amid stress and anguish. The role of Hannah Jelkes was written for Katharine Hepburn, but Spencer Tracy needed her care; Margaret Leighton played it and won a Tony. Bette Davis, difficult to imagine as the sensual Maxine Faulk, was at her most tyrannical during tryouts; she left the production after three months. Elia Kazan didn’t direct, though he lauded the work of Frank Corsaro, who did. In the end, however, the play survived, but La Femme Theatre Productions’ revival, the first in 28 years, demonstrates that pitfalls abound.
