The Brady Kids

The Brady Kids is an American animated television series and a spin-off based on the ABC live-action sitcom "The Brady Bunch", produced by Filmation in association with Paramount Television. It aired on ABC from September 9, 1972, to October 6, 1973, and also spun off another Filmation series, "", starring Rick Springfield.
Background.
In 1972, with the live action sitcom "The Brady Bunch" preparing for the start of its fourth season, show creator and executive producer Sherwood Schwartz approached Filmation about the creation of an animated series featuring the Brady Kids. Filmation agreed, and Lou Schiemer and Norm Prescott (who would later develop Schwartz properties "Gilligan's Planet" and "The New Adventures of Gilligan") headed up the project.
Characters.
The original show's six children (Barry Williams, Maureen McCormick, Christopher Knight, Eve Plumb, Mike Lookinland and Susan Olsen) voiced their animated counterparts in the first season. As the series' title implies, the parents and Alice the housekeeper characters were omitted from the show. At the end of the first season, Filmation asked the kids to continue on their existing contracts for another five episodes in a second season. The kids' original answer was no, prodded on by their agent Harvey Shotz. Filmation threatened both to sue the children over breach of contract, and to continue the show without their voices. Lookinland, Plumb, and Olsen agreed to the extended Filmation contract, while Williams, Knight, and McCormick did not. Williams's and McCormick's voices were replaced by the children of producer Lou Schiemer (Lane and Erika Scheimer, respectively), while Knight's voice was replaced by David E. Smith.
The animated series also added some animal characters. Marlon (voiced by Larry Storch) was an intelligent, red, talking mynah bird and also a wizard who used his magic to help the kids out of jams. Marlon was also notable for his method of flight: he spun his tail feathers like a helicopter rotor rather than using his wings, which were instead used as hands, often for grand gestures as he cast spells.
The Bradys' dog from the live-action series, Tiger, was replaced by a dog named Mop Top (also voiced by Storch). There were also twin giant panda cubs, Ping and Pong (voiced by Jane Webb), named after the game ping-pong. The pandas only spoke in a Chinese-like gibberish.
There were three human characters created for this show: Chuck White (Storch) was a boastful, self-absorbed teenager (about Greg's age) who was not above cheating to get whatever he wanted, Fleetwood (Storch) was his easygoing sidekick and rounding out this trio was Babs (voiced by Webb), a cute redhead who was smitten with Greg. The three of them went to the same school as the Bradys, and Chuck was sometimes central to the plot as an antagonist.
Production.
While Schwartz originally intended to hand off full editorial control to Schiemer and Prescott, he eventually returned to become an active part of production, reviewing scripts and advising on creative input.
Much of the animation for the series was copied over from another Filmation series, "The Archie Show". Walk cycles, profile pictures, and scenes where the Brady kids play in a band were all frame-by-frame replacements for looped frames originally seen of The Archies on "The Archie Show". Many of Mop Top's poses were copied from the Archies' character Hot Dog. Fleetwood's poses and walk cycles were often copied from Rudy of "Fat Albert and the Cosby Kids".
Originally aired as a one-hour segment on "The ABC Saturday Superstar Movie", the pilot episode was split into two half-hour segments on "The Brady Kids". A total of 22 episodes were produced. Season 1 aired Saturday mornings from 10:30 to 11:00 AM, and season 2 aired Saturday mornings from 11:00 to 11:30 AM. Season 1 contained 17 episodes, and season 2 contained 5. Season 2 was specifically created by Filmation with the intent on 5 episodes to bring the total count of episodes to 22, the minimum required for syndication. Like most 1970s-era Saturday morning cartoon series as well as "The Brady Bunch" show itself, "The Brady Kids" contained an adult laugh track.
The opening sequence featured the fourth season "grid" familiar to "The Brady Bunch" viewers, without the center column that is normally occupied by the adults (Mike, Carol and Alice). Near the end of the theme song (featuring new lyrics set to the original "Brady Bunch" theme with a 70's style beat), Marlon flies up and down the center, "magically" transforming the live-action children into their animated counterparts. Another intro features Marlon flying up and down the center of an empty blue background to reveal the Brady Kids.
