Jim Henson made two films for the fascinating series NBC Experiment in Television: "Youth ’68: Everything’s Changing … Or Maybe It Isn’t" (dir. Jon Stone, 60 mins.) is a montage of interviews with people from all walks of life, creating a time capsule of 1960s lifestyles. In "The Cube" (dir. Jim Henson, 53 mins.), a man trapped inside a white cube faces strange questions about the nature of existence, and a lot of odd characters who only add to the mystery.
