The War Between the Tates is a diluted but still enjoyable TV-movie adaptation of Alison Lurie's satirical novel. Elizabeth Ashley plays Erica Tate, a middle-aged suburban homemaker. Richard Crenna is her professor husband Brian Tate. When Erica runs across evidence that Brian is conducting an affair with a nubile co-ed (Annette O'Toole), Brian promises he'll cease and desist, but doesn't. Already suffering an ego crisis due to the affair, Erica finds her emotions churned up further when she meets her husband's pregnant girlfriend--an eminently likable creature whom Erica cannot bring herself to despise. Though set in a midwestern college town, The War Between the Tates was filmed in Toronto.
