There’s nothing like a white slavery scandal to intensify what could have been just another musical about a farm girl in Manhattan. This adaptation of Richard Morris’s 1967 screenplay travels easily to the intimate Marriott stage in a production led with lanky charm by Tari Kelly as Millie, supported by an attractive, nimble-footed ensemble. At two and a half hours, the show could afford to have a few reprises cut. Doing so might allow time to savor the dramatic climax–the villain’s comeuppance–treated here as an afterthought, a break between tap dances. Or if beguiling tenor Brian Herriott and jazzy sensation E. Faye Butler could somehow be given more to sing, no one would leave feeling disappointed. Through 4/23: Wed 1 and 8 PM, Thu-Fri 8 PM, Sat 5 and 8:30 PM, Sun 1 and 5 PM, Marriott Theatre in Lincolnshire, Rte. 21 (Milwaukee Ave.), Lincolnshire, 847-634-0200, $42-$45.
