In Summer 1994, this lost pilot aired on the Cartoon Network, and was released with the First Season DVD set. This was the original pilot episode for 'The Flintstones', but was never shown with the original series. It was actually a 90 second "demo reel" (with greasepencil marks still visible on the film), designed to sell the series to potentail advertisers in the winter of 1960, depicting a scene from what would eventually become the episode "The Swimming Pool". Kenneth Muse was the animator for this film reel.
