The Green Promise is a 1948 American drama film directed by William D. Russell. The film was co-produced by Houston oilman Glenn McCarthy and leading man Robert Paige to display the concept and meaning of the 4-H Club and highlight farming issues such as soil erosion, government programs, and individual enterprise. The title refers to a scene where the local preacher gives a sermon on a story from the Book of Exodus of God's "green promise" to lead Moses into a land of milk and honey. The preacher reminds his congregation that the fulfillment of the promise requires faith, difficult journeys and open-mindedness.

Plot: Mr. Matthews (Walter Brennan) is a farmer who is constantly being encouraged to update his work practices with newer technology. Staunchly dedicated to the time-honored methods that he knows, Matthews, a widower, raises his family in a similarly old-fashioned manner. Over time, his extremely stubborn ways begin to alienate his children, who are growing up whether he likes it or not. Eventually, he has to learn to loosen up and change with the times or risk pushing his kids away.
