The Cottage may look like a throwback to the tony sauciness of Noël Coward’s plays in the 1930s—in a nod to the Master, Beau’s secretary is named Mrs. Worthington—but it is broader in character and characters, and less sophisticated in language. Some of the play’s biggest laughs come from outright spoofery of its period and genre, like a running joke that finds cigarettes and lighters concealed in unexpected parts of Paul Tate dePoo III’s well-stuffed set. (These cigs rarely stay lit for long; they are alway being stubbed out in some dramatic gesture.) Amid the old-fashioned trappings, Rustin nestles a welcome modern sensibility to the plot’s skirmishes of the sexes; Sylvia’s dissatisfaction hints at the growing agency of post-Victorian Englishwomen. While the architecture of the plot is solid, what really keeps The Cottage up is the comedic industry of its cast. Directed by Jason Alexander, a seasoned hand at classic timing, the actress leap gamely into their funny business. McCormack’s vain Beau is smoothly caddish and twittish; Moffat, leading with his chin, has some inspired physical horseplay, and Steingold packs a lot of power into her small frame. And Bundy, who looks smashing in Sydney Maresca’s costumes, holds the play’s center together with considerable appeal. It’s sex, sure, but more than that: It’s charm.
