Lovin' Molly is basically Jules and Jim, Texas style. In 1925, two close friends (Anthony Perkins and Beau Bridges) both fall in love with prescient woman's-libber Molly (Blythe Danner). Molly in turn loves both men equally and can't choose between them, so the three set up a freewheeling menage a trois--which endures for nearly forty years. Lovin' Molly belongs to Blythe Danner, an otherwise overly mannered actress who is at her naturalistic best herein. Lovin' Molly was based on the novel Leaving Cheyenne by Larry McMurtry.
