These movies featured a slightly older version of the original five-character cast from the "Scooby-Doo, Where Are You!" days. The first four DTV entries were "Scooby-Doo on Zombie Island" (1998), "Scooby-Doo! and the Witch's Ghost" (1999), "Scooby-Doo and the Alien Invaders" (2000), and "Scooby-Doo and the Cyber Chase" (2001). Frank Welker was the only original voice cast member to return for these productions. Don Messick had died
