After the first Scooby-Doo TV series went off the air, CBS transitioned the detective dog over to The New Scooby-Doo Movies, which was a bizarre showcase that teamed the pooch and his crew up with a different celebrity guest star every week. Selected from the cream of the crop, early 70s edition, the guests included Sonny and Cher, Dick van Dyke and Don Knotts. Fictional characters also came in to solve crimes, including the Addams Family and, of course, Batman and Robin. The Dynamic Duo actually teamed up with the Scooby Gang twice.
