Keep Circulating the Tapes: After Warner Bros. released the 1960s episodes on DVD, it took another five years for them to start releasing the '80s seasons on that format, and yet another five years for them to complete that era. Additionally, the latter 2/3 of the revival, including the TV specials The Jetsons Meet the Flintstones and Rockin' with Judy Jetson, became available only through the Warner Archive.
Lucille Bliss recorded six weeks of dialogue for Elroy before being fired by due to behind the scenes controversy. Daws Butler would voice the character for the series proper.
Morey Amsterdam and Pat Carroll were initially cast as George and Judy Jetson, but only recorded one episode before being replaced by George O'Hanlon and Penny Singleton due to sponsor conflicts with the actors' previous commitments (Amsterdam on The Dick Van Dyke Show and Carroll on Make Room for Daddy). Both sued Hanna-Barbera for breach of contract, having been guaranteed the full 24-episode season, but the court ruled in favor of the studio.
Janet Waldo recorded her dialogue as Judy for The Jetsons Movie, but was redubbed by pop singer Tiffany (who originally only did the singing) in post production.
Recycled Script: The episode "G. I. Jetson" is basically the plot of "Uniblab" in a military setting.
Screwed by the Network: The original series lasted just one season because ABC didn't require affiliates to broadcast the series in color, causing many who did see the series be appalled by the futuristic setting without any color to go with it. It ultimately found success in syndication, which was, for many, the first time people watched the series (and in its original color form, no less).
Vindicated by Reruns: The original ABC run flopped after one season but managed to find huge success on syndication, to the point where many wished ABC rolled out the color television carpet sooner rather than later.
On certain episodes of the 80's series, John Kricfalusi was the animation director or layout supervisor. Hallmarks of his style would become more apparent, in his later original creation, The Ren & Stimpy Show.
Outlived Its Creator: Again, just like The Flintstones Stone Age Smackdown, this is the first original Jetsons production to not involve the original creators (William Hanna and Joseph Barbera, who passed away in 2001 and 2006, respectively). It's also the first one since Jetsons: The Movie from 1990.
Playing Gertrude: We have an interesting case with Jane. She's voiced by Grey DeLisle Griffin (who was born in 1973), which makes her two years older than Judy's voice actress, Danica Mc Kellar (who was born in 1975). However, Grey is one year younger than Elroy's voice actor, Trevor Devall (born in 1972), and 13 years younger than Jeff Bergman (voice of George and Mr. Spacely, who was born in 1960).
Role Reprise: Jeff Bergman fills in for George and Mr. Spacely entirely after voicing them for a couple lines in the previous movie.note Jeff Bergman had in fact took over as the characters for many minor works such as the Spumco shorts and various commercials prior to this, but this was his first prominent role
