Scooby-Doo and the Cyber Chase is the fourth of a series of direct-to-video animated films based on Hanna-Barbera's Scooby-Doo Saturday morning cartoons. It was released on October 9, 2001. It features the Mystery, Inc. gang, which includes Scooby-Doo, Shaggy, Freddy, Daphne and Velma. As is the case with all Scooby-Doo-related projects, the film is produced, starting in 2000, by Warner Bros. Animation, yet carries a Hanna-Barbera Cartoons, Inc. copyright and logo. It is recognized as the last "official" Hanna-Barbera production, as Warner Bros. had fully absorbed Hanna-Barbera after the passing of founder and creator William Hanna. It is the fourth and final Scooby Doo direct-to-video film to be animated overseas by Japanese animation studio Mook Animation. This movie, along with Aloha, Scooby-Doo!, was part of the first Scooby-Doo re-release on Blu-ray on April 5, 2011.
