Fantastic Voyage is an American animated science fiction TV series based on the famous 1966 film directed by Richard Fleischer. The series consists of 17 episodes each running 30 minutes. It was run on ABC-TV from September 14, 1968 through September 5, 1970. The series was produced by Filmation Associates in association with Twentieth Century Fox, and was the story of the C.M.D.F. (Combined Miniature Defense Force), a secret United States government organization which possessed the ability to reduce people to microscopic size. The characters were Commander Jonathan Kidd; biologist Erica Lane; scientist Busby Birdwell; and a master of mysterious powers known as Guru. The team was reduced in size and traveled around in a microscopic flying submarine, the Voyager, doing battle against the unseen, unsuspecting enemies of the free world (both criminal and germinal matter). The series featured the voices of Marvin Miller, Jane Webb, and Ted Knight. The producers were Lou Scheimer and Norm Prescott, the director was Hal Sutherland, and the music was provided by Gordon Zahler.

    Ted Knight, who provided character voice and narration, is most famous for playing Ted Baxter on The Mary Tyler Moore Show.

    In the motion picture, the initials CMDF stood for Combined Miniaturized Deterrent Forces. The producers felt that most kids wouldn't understand the word 'deterrent' and changed the initials to mean Combined Miniature Defense Force.

    Despite the series only running 17 episodes (one season), Aurora Model Company produced a plastic model of the Voyager in 1970. This kit received only one press run, and as a result is one of the rarest kits to find of the Aurora line. Unbuilt, in-box kits have been sold on eBay usually between $300 - $700.00 USD, while assembled to partially versions in varied conditions ranging from "acceptable" to "well-worn" - have been sold for in excess of $100, depending on condition. Polar Lights, a company which owned the rights to re-produce the kit passed on re-releasing the subject. Company director Dave Metzner stating that they had to produce much more in-demand subjects in order to be able to afford even considering the production of such niche products.
