Moss Hart's sharp, hard-boiled 1946 farce Light Up the Sky is the quintessential backstage tale of the mid-20th century. His characters are often based on real people: fast-talking producer Sidney Black (Benjamin Burdick) and his sassy ice-skater wife, Frances (Andrea Syglowski), are almost certainly meant to suggest Mr. and Mrs. Billy Rose. The characters are types, but Hart transmutes them into archtypes, readily recognizable to those too young to remember the era they represent. We meet them in a hotel in Boston, where they're preparing for the out-of-town opening of a show they hope will go off “like a roman candle in the tired face of show business.” There's the self-dramatizing star Irene (Laura Flanagan), her dim-bulb husband (Richard Michael Knolla), and her earthy, disenchanted mother (Barbara Schofield). The pretentious, over-emotional director (Colin Campbell) is said to cry at card-tricks, and the callow young playwright (Dominic Spillane) must undergo his theatrical baptism by fire. Hart's script crackles with wit and wise-cracks, and, under the clever direction of Bjorn Johnson, the laughter is near-constant on Victoria Profitt's art-deco set. Burdick is a dynamo of verbal pyrotechnics, and he's evenly matched by most of the cast, who make the most of Hart's cynical/sentimental Valentine to show business.
