Cartoon Network’s The Scooby-Doo Projecta ten minute long parody of the then huge hit The Blair Witch Project, the short uses the ‘98-‘99 voice cast (The “Zombie Island” Voice Cast) and unusually animates the gang against real world footage of various locations. It has never been released on DVD or Blu-Ray, possibly because it holds the dubious honor of being the one of the most complained about shows in Cartoon Network’s history.
the motion tracking on those characters is amazing especially for something from 1999
