Hemo the Magnificent is an examination of what the circulatory system is and how it works. It was written and directed by Frank Capra, and starred Frank C. Baxter as Dr. Research, Richard Carlson as the Fiction Writer, Mel Blanc as the squirrel, June Foray as the deer, and Marvin Miller as Hemo. This film was first broadcast on March 20, 1957 at 9 PM. This was a better hour for a family program than used for Our Mr. Sun, and the program had more viewers than those being broadcast on the two other major television networks
