The New Scooby-Doo Movies is an American animated mystery comedy television series produced by Hanna-Barbera for CBS. It is the second animated television series in the studio's Scooby-Doo franchise, and follows the first incarnation, Scooby-Doo, Where Are You!. It premiered on September 9, 1972 and ran for two seasons on CBS as the only hour-long Scooby-Doo series. Twenty-four episodes were produced, sixteen for the 1972–73 season and eight more for the 1973–74 season.
Aside from doubling the length of each episode, The New Scooby-Doo Movies differed from its predecessor in the addition of a rotating special guest star slot; each episode featured real world celebrities or well known animated characters joining the Mystery, Inc. gang in solving mysteries. Some episodes, in particular the episodes guest-starring the characters from The Addams Family, Batman, and Jeannie, deviated from the established Scooby-Doo format of presenting criminals masquerading as supernatural beings by introducing real ghosts, witches, monsters, and other such characters into the plots.
The New Scooby-Doo Movies was the last incarnation of Scooby-Doo to feature Nicole Jaffe as the regular voice of Velma Dinkley, due to her marriage and retirement from acting.
