Here's another Scooby-Doo Movies entry from season 1, this one featuring the late Phyllis Diller in "A Good Medium is Rare".
Ms. Diller made her voice-over debut in the feature film, "Mad Monster Party", for Rankin-Bass, but this would be her only gig for Hanna-Barbera. A pity, in that the studio could've developed a series for her.
Following is a sample from the episode:
With Mystery, Incorporated having concluded its run recently, there's been some speculation about the next series. Count me among those who'd not mind a revival of the movie format, using current celebrities like NBA superstar LeBron James or the current incarnation of the Harlem Globetrotters. What do you guys think?
