The Doc and Sprocket sequences in the show were localized for each production country. In Germany and North America, Doc was an inventor. In the UK, Doc was changed to the Captain, a retired sailor living in a lighthouse, and in France, a chef. Most other countries chose to dub the original North American versions.
Only twelve of the 96 episodes shot for the UK version of Fraggle Rock were believed to survive in 2004, the rest having been junked with the demise of production company TVS in 1992. Many of the sales and production documents concerning the UK version also went missing. As such, British TV channels have had to make do with the original North American versions. Subsequent discoveries of off-air recordings have gradually reduced this number, until in December 2020, the Missing Believed Wiped group confirmed that all 96 episodes were now being preserved by the British Film Institute (BFI).
