The Betsy (1978)
An auto-dynasty family experiences scandal, adultery, incest and power struggles in a juicy adaptation of Harold Robbins’s best-selling novel. Ruthless patriarch Loren (Laurence Olivier) hires racecar driver Angelo (Tommy Lee Jones) to build a more efficient vehicle against the wishes of his grandson (Robert Duvall). But things get even messier when Angelo romances two women in Loren’s life — his great-granddaughter and his mistress.
