Lake Bell’s comedy I Do . . . Until I Don’t opens with a God’s eye view of a funeral. Mourners hold oddly colorful umbrellas while a drizzle falls and, in voice-over, a woman with an English accent intones a jeremiad against the “‘til death do us part” prison of marriage. There are several visual and thematic cinematic nods here, from The Umbrellas of Cherbourg to Four Weddings and a Funeral to, winkingly, Bell’s own In a World . . . (2013), a film about a woman breaking into the male-dominated world of voice-over narration. The tone of I Do . . ., however, is different from any of these—at least at first. Among the funeral-goers are Cybil (Mary Steenburgen) and Harvey (Paul Reiser), a married couple who spend most of their time sniping at each other about petty grievances. They are soon to be among the subjects of a documentary by filmmaker Vivian Prudeck (Dolly Wells), whose voice we heard over the opening shot. Prudeck is determined to expose what she sees as the bankruptcy of the institution of marriage by filming unhappy married couples and contrasting them with one happy unmarried couple in an open relationship. And so, as the film gets underway, we watch married people take potshots at each other, make brittle wisecracks at each other’s expense, lie to each other, and generally prove Prudeck’s thesis. We will have to wait for anything like the joy, warmth, or melancholy of Cherbourg or Four Weddings—or even the oddball wit of In a World . . .—until after Vivian’s monomania has nearly wrecked several relationships. Fortunately, the payoff is worth the wait.
