Pilgrims, you don't know how long I've waited for this one!
As we all know, Batman & Robin's 2 appearances on The New Scooby-Doo Movies in 1972 helped lay out the groundwork for Super Friends, which bowed a year later, over on ABC (Scooby was still on CBS at the time), but finding the two episodes intact has been harder to find than the proverbial needle in a haystack. Not anymore.
In both cases, the Dynamic Duo & Mystery, Inc. joined forces against the Masked Manhunters' classic foes, The Penguin & The Joker. As was the case with Batman's 1968 animated series from Filmation, also for CBS, there has been some debate as to who actually voiced the Joker, be it Ted Knight or an uncredited Larry Storch. Seeing as how Joker has more of a Bogart-esque lilt to his voice, neither actor even tried to replicate Cesar Romero's portrayal of the Clown Prince of Crime from the live-action Batman. Knight was credited with doing Penguin, which I find a little hard to believe, to tell you all the truth.
Anyway, here's "The Dynamic Scooby-Doo Affair". Note that the open appears to be the original, as opposed to the edited version used in syndicated repeats. Cartoon Network/Boomerang has the edited open, due to the fact that the robot gunman is shooting a gun into the air......!
Edit, 10/27/17: Unfortunately, the video has been deleted by Dailymotion, and no other copies are available at this time.
As soon as I find "The Caped Crusader Caper", that will pop up here, too. Now, if only I can find Superman's meeting with the Brady Kids........
