The Road to Wellville is a 1994 American comedy drama film written, produced and directed by Alan Parker, an adaptation of T. C. Boyle's novel of the same name, which tells the story of the doctor and clean-living advocate John Harvey Kellogg and his methods employed at the Battle Creek Sanitarium at the beginning of the 20th century.

Starring Anthony Hopkins, Matthew Broderick, Bridget Fonda, John Cusack, Dana Carvey and Colm Meaney, the film was shot in New Paltz, New York at the Mohonk Mountain House.

Dr. John Harvey Kellogg opened a sanitarium in Battle Creek, Michigan, where he practiced his unusual methods for maintaining health, including colonic irrigation, electrical stimulus and sexual abstinence, vegetarianism and physical exercise.

The sanitarium attracts well-to-do patients including William and Eleanor Lightbody, who are suffering from poor health following the death of their child.

On their way to Battle Creek they meet Charles Ossining, hoping to make a fortune by exploiting the fad for health food cereals.

His wife Eleanor, meanwhile, befriends Virginia Cranehill, who has a modern attitude toward sexual pleasure, influenced by the works of Dr. Lionel Badger.

Following the electrocution of a patient in the defective sinusoidal bath, and the discovery of yet another death, Will suffers a breakdown, flees the sanitarium, gets drunk and eats meat.

Writing in Bright Lights Film Journal, Tanfer Emin-Tunc commented: "It is a sophisticated blend of humor and documented historical material that seeks to question the various forms that race and class have assumed in twentieth-century American society.
