The Flintstones' New Neighbors was animated at Filman, an animation studio in Madrid, Spain (headed by Carlos Alfonso and Juan Pina) who did a lot of animation work for Hanna-Barbera between the early 1970s through the mid-1980s. This would explain why, artistically, the backgrounds in this special look very much like pencil and charcoal drawings, very different from the original series and its spin-offs.
Like many animated series created by Hanna-Barbera in the 1970s, the show contained a laugh track created by the studio, one of the last productions to do so.
Summary
The Flintstones and the Rubbles welcome a new strange family, The Frankenstones, to their Bedrock neighborhood.
The Frankenstones
The Frankenstone family featured on this special was a different version of the Frankenstones from the episode "Fred & Barney Meet the Frankenstones" of The New Fred and Barney Show (1979).
The new Frankenstone family members are:
Frank Frankenstone
Oblivia Frankenstone, his wife
Hidea Frankenstone, their daughter
Stubby Frankenstone, their son
A friendship develops between the Flintstones and the Frankenstones, not unlike the rivalry that would be depicted later between Fred and Frank on The Flintstone Comedy Show. This version of the Frankenstones continued to appear throughout the run of the specials.
On October 9, 2012, Warner Archive released The Flintstones' New Neighbors on DVD in region 1 as part of their Hanna–Barbera Classics Collection, in a release entitled The Flintstones Prime-Time Specials Collection: Volume 2. It was a Manufacture-on-Demand release, available exclusively through Warner's online store and Amazon.com.[2]
