Upper-class Manhattan wife-and-mom Dyan Cannon eschews libertine behavior; then mansplaining husband Laurence Luckinbill’s minor surgery becomes an extended hospital stay and she finds his little black book detailing his flings, spurring her to act out. Lois Gould’s comedy of manners novel was adapted by multiple screenwriters, including Elaine May—credited here as Esther Dale. The spot-on production design is by Rouben Ter-Arutunian (The Loved One).
