Journey to the Center of the Earth is an American science fiction Saturday-morning cartoon, consisting of 17 episodes, each running 30 minutes. Produced by Filmation in association with 20th Century Fox Television, it aired from September 9, 1967, to September 6, 1969, on ABC Saturday Morning. It featured the voice of Ted Knight as Professor Lindenbrook/Sacknussem. It was later shown in reruns on Sci Fi Channel's Cartoon Quest. It appears to have taken the 1959 film, Journey to the Center of the Earth, as its starting point rather than Jules Verne's original 1864 novel; e.g., including the character of Count Sacknussem and Gertrude the duck. However, it moved even further away from Verne's novel than the 1959 film did. There are currently no plans to release the series on DVD and/or Blu-ray Disc from 20th Century Studios Home Entertainment, although most of the series is available for viewing on YouTube.
