Many of the guest stars who appeared in The New Scooby-Doo Movies were living celebrities who provided their own voices (Don Knotts, Jerry Reed, Cass Elliot, Jonathan Winters, Sandy Duncan, Tim Conway, Dick Van Dyke, Don Adams, Davy Jones and Sonny & Cher, among others); some episodes featured celebrities who were retired or deceased, whose voicing was done by imitators (The Three Stooges and Laurel and Hardy), and the rest were crossovers with present or future Hanna-Barbera characters.

The USA Network Cartoon Express began running the New Movies in their original format beginning in September 1990; they were rerun on Sunday mornings until August 1992.

The Three Stooges are in danger when Curly Joe takes up a crop-dusting job on a farm haunted by the ghost of Baron Manfred von Richthofen.

Rock musician Davy Jones is the heir to Hagglethorn Hall, a haunted fortress that was brought over from the United Kingdom... but a phantom knight does not want him to take it over, so the gang help him solve the mystery while contending with a frog-like moat monster.

Scooby and the gang go to hear a concert by Jerry Reed, but discover he is missing and are told by Ben Bing and Bertha to leave the place because everything is fine.

While en route to the Tom Sawyer festival during a storm, the gang gets lost on the Mississippi River along the Illinois-Missouri border and wind up getting stuck on dock near an old haunted showboat, the Dixie Queen, where they bump into Josie and the Pussycats.

Jeannie brings Mystery, Inc. along for a time-travel trip to help stop Jadal the Evil Djinn's plan to thwart a young prince's elevation to sultan.

The gang help coach Tim Conway track down the ghostly athlete, Fireball McFain, who is haunting the students and faculty of Velma's alma mater.

The gang teams up with the Speed Buggy crew to find out why a town's population is suddenly declining, as they learn that something is strangely blowing in the wind and it is causing the residents to be fearful.

The opening titles on this release were edited to remove the images of the Addams Family, Batman and Robin, the Harlem Globetrotters, the Three Stooges, and Laurel and Hardy.

"The Secret of Shark Island" (featuring Sonny and Cher) episode was released in the U.S. and the U.K. on VHS on a video called Hanna-Barbera Presents: The Best of Scooby-Doo.
