Scooby-Doo
The first episode of "Scooby-Doo, Where Are You!" "What a Night for a Knight" debuted on the CBS network Saturday, September 13, 1969. The original voice cast featured veteran voice actor Don Messick as Scooby-Doo, radio DJ Casey Kasem (later host of radio's syndicated "American Top 40") as Shaggy, actor Frank Welker (later a veteran voice actor in his own right) as Fred, actress Nicole Jaffe as Velma, and musician Indira Stefanianna Christopherson as Daphne. Scooby's speech patterns closely resembled an earlier cartoon dog, Astro from "The Jetsons" (1962–63), also voiced by Messick. Seventeen episodes of "Scooby-Doo Where are You!" were produced in 1969–70. The series theme song was written by David Mook and Ben Raleigh, and performed by Larry Marks.
Scooby-Doo! and the Goblin King
Scooby-Doo and the Goblin King is a 2008 direct-to-DVD animated comedy horror fantasy film, and the twelfth in the series of "Scooby-Doo" direct-to-video films produced by Warner Bros. Animation (though it used a Hanna-Barbera logo at the end of the movie). It was dedicated to Paulette Oates, who helped resurrect Warner Bros. Animation in the late 1980s. All the main voice actors of Mystery, Inc. reprise their roles. The DVD was released on September 23, 2008. This is the first Scooby cartoon produced entirely without either one of the original creators, William Hanna and Joseph Barbera.
