State Fair (1976)

Set in Iowa, a dairy farmer (Tim O'Connor) and his wife (Vera Miles) must contend with a divorced daughter (Julie Cobb) and her troubled son (Jeff Cotler) as well as a teenage son (Mitch Vogel) in his first encounter with romance. Based on the novel by Phil Stong and directed by David Lowell Rich (MADAME X). This is the fourth version of the Stong novel which was previously made in 1933 and then as a musical in 1945 and 1962. However, unlike those three versions, it has very little in common with the book outside of its title. It was intended as a pilot for a TV series but it was never picked up and it's easy to see why. There's only about five minutes spent at the actual state fair and the bulk of the movie deals with the son's puppy love and the betrayal of the girl (Linda Purl) he's in love with. It's the kind of squeaky clean entertainment that gives wholesome movies a bad reputation. With Virginia Gregg and Dennis Redfield.
