In mid-16th Century France, a Duke brings his pregnant wife to the village doctor where she delivers twin boys--but the dotty nursemaid and the exasperated doctor mix the babies up with the newly-born twin boys of another couple, a peasant farmer and his wife, with each couple getting one correct child and one wrong. Thirty years later, the two sets of mismatched twins meet, but not before the peasants stage a revolt against bumbling King Louis XVI. Filmed entirely on location, this Bud Yorkin farce looks almost too good, too authentic for the pratfalls and slapstick nonsense which he stages on opulent castle grounds; the historic minutiae dwarfs the loosely-hinged plot, which isn't fully thought out to begin with. Worse, Gene Wilder and Donald Sutherland fail to become the Abbott and Costello team the filmmakers probably hoped they'd be. Wilder sticks to his short-fuse mania and gets off some big laughs, but Sutherland's preening fop/subdued street fighter never quite emerges as a three-dimensional character. Yorkin overdoses on swashbuckling action, a handful of riffs on Dumas, and some playful girl-ogling, yet at the expense of developing these characters (even the sequence where the peasant brothers are mistakenly brought to the castle falls flat on a narrative level, with a ruse about a violin case that feels pretty fatuous). However, there are several witty verbal duals which are smartly executed, and from a technical stand-point the film is keenly-judged--from the locations to the costumes to the music. But once the viewer realizes the movie is just a series of blackout sketches, the trimmings seem rather lofty and the frenzied footwork seems much ado about little. ** from ****
