La Vie a Deux on AllMovie

French filmmaker Sacha Guitry had intended to direct as well as write 3DLa Vie a Deux3D (3DLife as a Couple3D), but death claimed him before he could bring his plan to fruition. Adapted from Guitry's original by Jean Martin and directed by Clement Duhor, the film offers an all-star cast in a series of seriocomic anecdotes. The narrative is tied together by a millionaire novelist (based on Guitry himself), who on his deathbed wants to bequeath his fortune to several married couples upon whom he'd based one of his books. The proviso is that the couples must have remained happily wed to claim their money. The millionaire's family anxiously hire private detectives to prove that the couples in question are not only unhappy, but shameless philanderers in the bargain.
