A. T. and T. evidently had some kind of special educational campaign going on at the time. A 24-page booklet aimed at young people was copyrighted in late 1964.
Animation fans should like the cartoon segments which take up a good portion of the first half of the film. I especially like the designs of the circus animals about half-way through which teach us phone etiquette from the days before everyone carried around their own hand-held. Director Hubley’s career, which spanned and included the Disney strike, a McCarthyist ouster at UPA and Oscar wins as an independent producer, should be well-known to readers here. As for the voices, you’ll recognise Blanc doing a host of voices and Paul Frees as the sleepy bear and the fox (I should know who is doing the female voices but I don’t).
The opening theme is SF-1004 Happy Outing by Marc Lanjean. It’s originally from the KPM library but is found on Hi-Q reel L-95. The closing cue is Bright Title by Bill Loose and Emil Cadkin from the Capitol Production Music library. Spencer Moore’s L-1144 Animation Light makes an appearance during the running scene at the 2:30 mark and there are cues by Phil Green and some from the Hi-Q ‘D’ (Dramatic) series.
Mike Kazaleh helpfully listed some of the animators in a post on the late Michael Sporn’s blog, all veterans of the theatrical world.
The animators I can spot are Phil Duncan, Bill Littlejohn (these two did the most footage) Don Towsley (the lion and the raven), Emery Hawkins (the beaver and the bear), Ben Washam (the elephants) Tom Ray (the fox and the pig), and one other person I can’t identify (the Samuel Morse sequence.) Some of the stuff Duncan animated were the opening section, and the scenes of the ringmaster. Littlejohn animated the messenger traveling through time, and the two musicians.Oh, the little girl is Pamelyn Ferdin, who appeared on The Odd Couple and was one of the voices of Lucy in the Peanuts cartoons (which Littlejohn also worked on).
