She-Devil is a 1989 American black comedy film directed by Susan Seidelman and written by Barry Strugatz and Mark R. Burns. It stars Meryl Streep, Roseanne Barr (in her film debut) and Ed Begley Jr.. A loose adaptation of the 1983 novel "The Life and Loves of a She-Devil" by British writer Fay Weldon, "She-Devil" tells the story of Ruth Patchett, a dumpy, overweight housewife, who exacts devilish revenge after her philandering husband leaves her and their children for glamorous, best-selling romance novelist Mary Fisher.
