Yes, that's correct. Fulton MacKay played the lighthouse keeper, called 'The Captain' for the first 48 shows; following his death John Gordon-Sinclair and finally Simon O'Brien played similar roles.

The French version of the show was set in a bakery, and the German show had a similar character to the US - an inventor. Neither country completed the 96-episode run, though - only the US and UK versions did that.

The US shows have been released on DVD by HiT Entertainment and later Lionsgate in the US, and they're starting to appear in the UK now.
