I see, just because “The Flintstones” did something similar; they wanted to make a prequel!? The story of how Mystery Inc. was formed. The live-action cast features Robbie Amell as Fred, Kate Melton as Daphne, Hayley Kiyoko as Velma and Nick Palatas as Shaggy. Scooby-Doo was created using computer-generated imagery and his voice is provided by Frank Welker. The whole thing is about as forgettable as they come with no real impact. A bland recommendation for the fans of the animated series!
