Did You Know?


Initially Warner Bros. had planned a sequel to Scooby-Doo 2 (2004), but as the latter did not meet the economic rates expected by the company, it was decided to delay the project. It was not until 2007 when Cartoon Network executives offered support in the making of another live action film in the franchise, this time with a limited budget compared to the first 2 films and with a new cast, the original story was scrapped and it became a prequel.

In the scene in the library before the ghosts appear, it starts to get really cold. Shaggy breathes and you can see his breath. However, when the others in the room speak, you can't see theirs. See more »


Fred: So, the Bears really slaughtered those Dolphins last night, huh?
Shaggy: What? That's terrible! Who in their right mind would bring bears to the beach?

User Reviews

Stays true to the cartoon.
18 September 2009 | by sheer64See all my reviews

If you liked the cartoons you will like this movie. It is enjoyable and will keep the kids entertained. The story is simple the characters stay true to the cartoon ones and the best part is everybody loves Scooby Doo. This takes us back to when they first combine as an investigative group, having to defend their names at high school after some strange mishaps. I am not sure what the budget was on the film some simple effects have been used to keep production costs down. I give it a 6 out of 10 as it is lacking some substance, but still puts allot of bigger budget movies to shame. Overall worth watching with the kids and I hope they continue on and make more of this series.
