Gateways to the Mind is about what the five senses are and how they work. It was produced and directed by Owen Crump. The screenplay was by Henry F. Greenberg, a television screenwriter who was active in the 1950s and 60s. In addition to Dr. Baxter, it starred Wilder Penfield and Hadley Cantrell, with actor Karl Swenson playing the role of a cameraman (the program was set on a soundstage in a mock "behind-the-scenes" format).

In 1966, Jones won an Academy Award for Best Animated Short Film for directing The Dot and the Line: A Romance in Lower Mathematics

AT&T and N. W. Ayer were apparently somewhat dissatisfied with the first two Warner films, and unsuccessfully approached Capra about bidding on production of Thread of Life and About Time.

Owen Crump directed; Robert McKimson directed the animation.

About Time examines time. The screenplay was written by Richard Hobson, Nancy Pitt, and Leo Salkin. Owen Crump directed, with Phil Monroe directing the animations. The film starred Richard Deacon and Les Tremayne and featured Richard Feynman who was used as a consultant
