Doc, as sole human character on Fraggle Rock, was conceived as a personage who, framing the world of the Fraggles, could be altered and replaced in the different international versions of the series. Though an inventor in the North American series, suggestions for localized occupations included a toymaker, shopkeeper, lighthouse keeper, or even recast with an actress in the role. As far as is known, only three productions, those of France, Germany, and England, substituted their own versions of Doc. The lighthouse keeper, as used on the UK series, was the only suggestion adopted from the initial proposal. Other countries simply dubbed footage of the original Doc, Gerry Parkes.
