Lovers and Other Strangers became a "sleeper" hit, based on a play by Renée Taylor and Joseph Bologna. The story is essentially a series of vignettes and anecdotes, unified by an impending marriage. Father of the bride Hal (Gig Young) has problems with his long-suffering mistress, Cathy (Anne Jackson), who spends much of the film sitting on the toilet, crying her eyes out; Wilma (Anne Meara), the bride's sex-starved sister, can't wrest her husband, Johnny (Harry Guardino), away from the TV; and Frank (Richard S. Castellano), as the groom's father, slips comfortably into Bartlett's Familiar Quotations with his oft-repeated query "So what's the story?" Twelfth-billed Diane Keaton makes her film debut as a garrulous wedding guest.
