After completing filming for "Superman", Kidder starred as Kathy Lutz in the supernatural horror film "The Amityville Horror" (1979), which further cemented her status as one of Hollywood's leading ladies. "The Amityville Horror" was a major commercial success, grossing over $86 million in the United States, but it received mixed reviews from critics. Janet Maslin of "The New York Times", though giving the film a mixed review, said Kidder "stubbornly remains the bright-eyed life of the party the film." In retrospect, Kidder called the film "a piece of shit." The same year, Kidder hosted an episode of the American sketch comedy TV show "Saturday Night Live". On August 25, 1979, she married actor John Heard, but the couple separated only six days into their marriage. Their divorce was finalized on December 26, 1980.
