The Oldest Living Graduate(1980)

Henry Fonda stars as Col. J. C. Kincaid, crusty patriarch of a Texas family. Kincaid's weak-willed son Floyd (George Grizzard) wants to get into the old man's good graces so that he can develop the Colonel's vast land ownings. Floyd arranges a city-wide celebration lauding Kincaid as the oldest living graduate of a nearby military academy. The festivities serve only to make the already sour Kincaid even more truculent and miserable. Adapted from Preston Jones' 1974 play and originally telecast live from Dallas' Southern Methodist University on April 7, 1980.
