Henry Corden, who provided Fred Flintstone's (uncredited) singing voice, also voiced several incidental characters on The Flintstones and would later take over Fred's voice after 'Alan Reed''s death in 1977.
During the "Teammates" musical number, when Fred and Barney's airplane falls apart, it becomes the "Flintstone Flyer", the pedal-powered contraption featured in the very first episode of the series.
The airplane The Flintstones take to get to Paris has "Qantas" - the name of a real-life airline - written on the side.
The DVD was released outside the United States only, because Columbia Pictures owned the rights to the songs used in the movie. Only after the rights to the songs cleared in August 2008 was the movie released in the United States of America.
This movie was produced right after production of the original The Flintstones series ended, and was intended as a swan song for the characters.
Unusually, Wilma is seen wearing a blue dress in this film rather than her usual white.
