Like the chandelier in Phantom of the Opera, a revolving door is the all-purpose metaphor here. Luther Davis, who wrote the book for this 1989 musical version of the 1929 novel and 1932 film, has a mere 110 minutes to spin the show’s many intersecting stories, set in the world’s most luxurious hotel, so the door whirls fast. Michael Weber’s staging makes sense of and gives solidity to these glimpses of desperate souls on the eve of a depression and the Third Reich. Whether dancing the Charleston or lounging in Robert C. Martin’s gorgeous lobby, the large cast functions with Leona Helmsley-like efficiency. And James Harms gives the narrator, a world-weary war veteran, a potent moral authority. Through 11/6: Tue-Thu 7:30 PM, Fri-Sat 8 PM, Sun 2:30 and 7 PM. Also 2:30 PM Sat. Drury Lane Theatre Water Tower Place, 175 E. Chestnut, 312-642-2000. $35-$48.
