The first series was financed in part by RAI (Italian State Television), and was originally to have two Italian supporting stars (the pilot and Main Mission operative who later became Alan and Sandra respectively). The Italian title was "Spazio 1999". In addition to the series being shown on television, three episodes were edited together into a compilation and shown in cinemas: according to Keith Wilson, "the streets of Rome were empty because everyone was going to the cinema." The compilation used music from Ennio Morricone in place of Barry Gray's theme and some incidental music. The Morricone theme is available on the CD Time Of Adventure by Ennio Morricone (BMG 1997) 4321315512. (now out of print). The series on television had all the original music intact, with the exception of the Year 2 end titles, which were replaced by song S.O.S. Spazio 1999, performed by the Italian group Oliver Onions.
The Year One episodes were shown on the RAI channel in 3 blocks: the first 6 episodes from Saturday 31st January 1976 at 10pm, the second block of six from Thursday 1st July at 8:45pm, then the remaining 12 from Sunday 24th October to January 9th 1977 at about 6pm. In 1979 Year 2 was broadcast on RAI channel 1 from April 6 at 5pm. Episodes were broadcast in two parts, one part a day, Monday to Saturday. For some reason "The Bringers of Wonder" was not included in the first run of season two and was aired only some time later.
In the Italian version Dr. Russell is HELEN not Helena. This is probably due to the fact that HELENA sounds exactly like the Italian name ELENA. The people who supervised the Italian version probably thought this was too Italian for an American character(!) In year two Tony's last name is pronounced VERDESKI which is the correct Italian pronunciation for VERDESCHI.
The Italian fan club Moonbase '99 has organised a number of conventions in Italy.
There was also a poster for the 1975 Spazio 1999 movie.
