Screwed by the Network: The film never got a theatrical release in the USA as the Canadian territory was sold during post production, and the new owners decided it wasn't worth investing in an American run.
Creative Differences: The simple reason as to why Ronnie James Dio left Rainbow after Long Live Rock n Roll. Dio didn't want anything to do with the commercial direction Ritchie Blackmore was taking the band in.
Keep Circulating the Tapes: The band's last album Stranger in Us All has never seen a re-release and has also never been made available on iTunes, making it surprisingly hard to find in lossless quality.
Currently averted as it has since been made available for purchase on iTunes.
Keep Circulating the Tapes: To celebrate its 30th anniversary, six episodes were released on DVD. Apart from a few other compilation DVDs from the same company that featured other shows, for a while there weren't many Rainbow episodes available to see, apart from taped episodes by viewers at the time of airing on video sites. However, there is now an official Rainbow channel on Youtube which has been uploading episodes, including the entirety of the rarely-seen first series. Unfortunately, said channel has been taken down, although re-uploads can currently be found on Dailymotion.
The Other Darrin: For the first season, Zippy was voiced by Peter Hawkins, before Roy Skelton took over in 1973 once his popularity exploded and Sunshine and Mooney were given the boot.
Talking to Himself: Roy Skelton voices both Zippy and George, and continued doing so up to his death in 2011.
Throw It In!: In a scene in the episode Night Out, Zippy knocks a nearby washing up liquid bottle over and it rolls onto the floor. This scene was kept in, and in the next shot, it had been put back on the table as if it never got knocked over.
What Could Have Been: According to Word of God, Zippy was originally going to have a mother and father, who had zip compartments in their side and stomach respectively. However, only Zippy made the final cut.
