Mistaken identities, outrageous plot twists, slapstick comedy and a slew of self-obsessed performers desperately try to keep things from falling apart. It’s all in a day’s work for master of the period-perfect farce Ken Ludwig (Lend Me a Tenor). In this fast-paced comedy set in Buffalo in 1953, a husband-and-wife acting team with a crumbling marriage struggle to keep their repertory ensemble together long enough to allow famed director Frank Capra to see them perform. But with a pregnant ingenue, a drunk leading man and a surprise visit from their daughter, things quickly go horribly (and hilariously) wrong. The original Broadway run of Moon Over Buffalo starred Carol Burnett and ran for more than 300 performances, and now it’s coming to the Patio Playhouse in Escondido.
