Goof: Elroy's cap briefly changes to red and back to green when he bounces on his pogostick.
Goof: After George bumps into the front door on his way out, the next shot on Jane shows her dress as rose-colored instead of its usual shade of purple.
Goof: Judy's red headband changes twice to black when she's on the exercise bike next to Rocky Retro.
Goof: When the employment agency's robot barges into the Jetsons' apartment, Judy's hair is colored orange in at least three shots when she's asleep on the sofa.
Rocky Retro's voice is provided by Jerry Dexter, who's teamed with Janet Waldo (voice of Judy) on a number of Hanna-Barbera series, including Shazzan and Josie and the Pussycats.
While Judy is walking the dogs, a cat runs by. The dogs start running fast and pull Judy out of her shoes. She is still barefoot in the next scene. Finally, this common shoe nitpick is avoided!
