Stanley Tucci makes a slam-bang Broadway directing debut, with the brio and instinct for timing that you would expect from a seasoned actor. He has, moreover, inspired a cast of comic equals (even in the smaller roles) to harmonize the insanity, land the gags and top each other for the daffy monomania that is the sine qua non of farce. And what a vehicle they have: Ludwig’s old-fashioned screwball door-slammer is structurally perfect, all missed connections, mistaken identities, girls hiding in closets and an enraged impresario throttling his deceased tenor—multiple times.
