The Road to Wellville is a satirical comedy-drama film released in 1994. It is loosely based on the novel of the same name by T. Coraghessan Boyle. Set in the early 20th century, the movie tells the story of two couples - the Perkinsons and the Lightbodys - who visit John Kellogg's infamous Battle Creek Sanitarium, also known as the Kellogg spa.
William and Eleanor Lightbody (played by Matthew Broderick and Bridget Fonda) are a young couple from a wealthy family who are deeply unhappy in their marriage. They hope that a stay at the Kellogg spa will help them feel better and rekindle their love for each other. However, their relationship becomes more strained as they undergo bizarre treatments and follow a strict diet imposed by Dr. Kellogg (played by Anthony Hopkins).
Meanwhile, Charles Ossining (played by John Cusack) is a young entrepreneur who is trying to break into the highly competitive breakfast-cereal business. He meets Dr. Kellogg and pitches his own brand of corn flakes, but is rebuffed. As he struggles to get his business off the ground, he becomes involved with Ida Muntz (played by Dana Carvey), a fellow patient at the sanitarium who is a con artist pretending to be dying of terminal cancer.
The film also features the eccentric Dr. Lionel Badger (played by Michael Lerner), who is a rival of Dr. Kellogg and runs his own less-restrictive health spa. The two doctors engage in a bitter rivalry and sabotage each other's business.
Overall, The Road to Wellville is a quirky and entertaining film that skewers the health fads and social mores of the early 20th century. It received mixed reviews upon its release but has since gained a cult following.
