Filmation Associates, the studio that produced the animated Saturday morning version of Fantastic Voyage made some minor changes. General Carter from the movie version became Professor Carter in the animated version. The submarine that the crew used to miniaturize in the movie version which was called the "Proteus" was changed for the animated version. The submarine was changed to an aircraft that also had underwater capabilities and christened the "Voyager." The movie name of the government agency was called the "Combined Miniature Deterrent Force." However, for the animated series, the name was changed to the "Combined Miniature Defense Force."
