But there was a tele-film produced for Cartoon Network back in 2001 called "The Flintstones on the Rocks". That should be available on DVD as soon as possible.
Here is a little bit of information I found on the feature at http://www.topthat.net/webrock/specials/OnTheRocks.htm :
The first animated Flintstones incarnation done in several years, this tele-film actually captures the essence and flavor of the original series. The animation is raw and expressive -- patterned after early episodes of the The Flintstones, and the voice actors pull off an amazing job. The decision to bring in new actors was wise; listening to Jeff Bergman and Kevin Michael Richardson, you'd almost swear the banter was between Alan Reed and Mel Blanc returned to life. The same can be said for Grey Delisle, who actually comes closer to the original giggly Betty than we've seen so far, and Tress MacNeille sounds strikingly like the nasally Wilma of yesteryear.
The simplicity of the series is back, with even the Flintstone home returning to its original shapeless rock cave, and the streets and background cleaned up.
And probably most important here, The Flintstones On the Rocks is written in a way that adults would again appreciate it, with dialogue that is humorous and appealing -- and even suggestive!
This would be a great addition to the Flintstones DVD library! Come on Warners, what do you say?
