The first of Hanna-Barbera's 1970 freshman class was also their last primetime entry for a few years.
Where's Huddles was a summer replacement for The Glen Campbell Goodtime Hour from July-September 1970, and then resurfaced a year later as filler following NFL football. It was in the latter case where I first discovered the show.
The series was a more modern-day reworking of The Flintstones, but this time instead of working in construction, Ed Huddles (Cliff Norton) and Bubba McCoy (Mel Blanc) were football players. A neighbor, Claude Pertwee (Paul Lynde, Hollywood Squares, Bewitched) wasn't much of a football fan, as he'll readily admit in the open, uploaded by cartoonsintros:
Only 10 episodes were produced, and after its Sunday run, the series was never seen again until picked up by Boomerang a few years ago. In this writer's opinion, Huddles could be redone for a modern audience, with more of an emphasis on family rather than career. Problem is, it was not too successful the first time around, so I doubt that Warners might be willing to take a flier on it more than 40 years later.
