Happy as the Grass Was Green

Happy as the Grass Was Green, later renamed Hazel’s People, is a 1973 American drama film directed by Charles Davis and starring Geraldine Page, Pat Hingle and Graham Beckel. The film is one of the few Old Order Mennonite related films ever made.
Most of the cast other than the aforementioned consists of genuine Pennsylvanian Mennonites. The film is based on a novel by Merle Good. For many years, the film was presented nightly at the "People's Place" in Intercourse, Pennsylvania. The Global Anabaptist Mennonite Encyclopedia Online states: "The two films "Amish Grace" and "Happy as the Grass was Green" have significant insider Mennonite contributions and come closest to presenting a valid image of Amish and Mennonites".
The original title of the film is taken from the poem "Fern Hill" of Dylan Thomas.
Plot.
A Mennonite family's son is beaten to death at an unnamed New York university protesting the Vietnam War. His best friend and another college student, Eric Mills, portrayed by Graham Beckel, attend his funeral in the Mennonite country in Pennsylvania. Once Mills arrives in the small town, he connects with the simple lifestyle there and discovers the Christian faith of the Old Order Mennonites. In the end, he decides to join the small, devoutly religious community.
