Hemo the Magnificent is a one-hour Technicolor made-for-television educational film, released in 1957 by Bell Laboratories and directed by Frank Capra, and first telecast by CBS.
Several well-known voice artists were employed for the animated sequences, including Marvin Miller as the title character, Hemo.
Although Time magazine gave it an extremely negative review,[2] calling it "condescending" and citing it as an example of how the scientific information was presumably "dumbed down" by including cute cartoon animals, it quickly became a classic of the genre, featuring incredibly detailed television animations for its time.
Hemo the Magnificent and another Bell Laboratories film, Our Mr. Sun, were favorites for showing in school science classrooms.
One of the evil gremlins sneaks into a classroom while the science teacher (Glynn Turman) is showing Hemo to the class.
