This series and La fantastica Jeannie (1973) are each wholly owned by Screen Gems (now Sony Pictures Television Studios), making them among the few Hanna-Barbera series owned by an outside studio.
This series was originally intended to be a second Jetsons series, but it was changed to feature the Partridge family instead. This is why Reuben Kincaid looks like an older George Jetson.
Susan Dey only voiced Laurie Partridge in "Danny the Invisible Man" and "My Son, the Spaceball Star." Sherry Alberoni, who voiced Alexandra for Hanna-Barbera's "Josie and the Pussycats" and Wendy for "Superfriends," played Laurie in the remaining episodes. John Stephenson voiced Reuben Kincaid instead of the original series' Dave Madden. Suzanne Crough and Brian Forster returned for their roles of Tracey and Chris, respectively.
Final Hanna-Barbera cartoon produced by Screen Gems (later Sony Pictures Television), prior to its acquisition from Taft Broadcasting in 1966 in particular.
