Writer/director Alan Parker spoofs modern diet crazes with a look back to the early 1900s, when physician/inventor/cereal pioneer Dr. John Kellogg (Anthony Hopkins) lured the rich to his Michigan sanitarium/spa for a bizarre--and sometimes fatal--regimen of exercise, health food, sexual abstinence and enemas. Based on T. Coraghessan Boyle's novel, the offbeat comedy also stars Bridget Fonda, Matthew Broderick, John Cusack and Dana Carvey. 120 min. Standard; Soundtrack: English Dolby Digital Surround; Subtitles: English; theatrical trailers; interactive menus; scene access.
