The October 1981 issue of Vogue magazine features Nastassia Kinski on the cover and includes the infamous Richard Avedon two-page photo spread of the actress wearing nothing but a huge, writhing boa constrictor. But in the alternate reality of Caitlin Saylor Stephens’s vitriolic new comedy, Five Models in Ruins, 1981, that October issue very nearly comes to feature a much lesser-known cover girl, and the accompanying story would showcase not a serpent, but five decidedly catty women in flowing white gowns.

Ryan J. Haddad’s Hold Me in the Water, like the dramatist himself, is charming and effervescent. Also like Haddad, it’s slender (though that word has different connotations when applied to the human form and to an Off-Broadway play).

The Mistake is a gripping and powerful examination of the decisions that went into the development of the atomic bomb and its initial deployment on Hiroshima. Written by cast member Michael Mears and directed by Rosamunde Hutt, the play is an unflinching look at the emotional and physical destruction of scientific breakthroughs when they are used to stop a war, as told by the inventor of the nuclear chain reaction, Leo Szilard.

Three of Britain’s leading comedians of the 20th century are the focus of Paul Hendy’s The Last Laugh, a play that harks back to Sutton Vane’s Outward Bound (1923) and Trevor Griffiths’ Comedians (1975). As the trio meets in a shabby dressing area of an uncertain venue for some kind of benefit performance, issues of what makes something funny and who steals jokes from whom, along with plenty of comic insults, arise.

Mona Pirnot’s new play, I’m Assuming You Know David Greenspan, concerns the hardscrabble existence of aspiring playwrights and the passion that keeps them writing for an industry in which, as playwright Robert Anderson ostensibly said, it’s possible to make a killing but never a living. David Greenspan is the very model of a theater artist who has persevered despite dire fiscal odds. Greenspan is pretty well-known Off-Broadway and, especially, Off-Off Broadway, but he’s certainly not a household name.

In 1969 the two-year-old Negro Ensemble Company mounted the off-Broadway premiere of Lonne Elder III’s Ceremonies in Dark Old Men. “A remarkable play,” raved Clive Barnes in the New York Times. Now, in a joint presentation with the Peccadillo Theater Company and producer Eric Falkenstein, the NEC revisits this gut-punch period piece, offering a rock-solid production that hums along toward inevitable tragedy, chronicling the socioeconomic plight of Harlem in the 1950s through the deeds and decisions of one troubled family.
