Deliberate mistake: In the first scene Velma gets sprayed by the hose and slips but gets her foot caught on the chain; hanging upside down, but her skirt doesn't go "up". Deliberate to maintain the "family movie" tone. (00:02:40)
Scooby-Doo (2002)
1 deliberate mistake
Directed by: Raja Gosnell
Starring: Matthew Lillard, Rowan Atkinson, Sarah Michelle Gellar, Isla Fisher, Linda Cardellini, Freddie Prinze Jr.
Continuity mistake: In the beginning of the movie during the skateboard scene with Shaggy and Scooby riding along the conveyor belt, Scooby grabs a hook and both Shaggy and Scooby jump off of the skateboard. You see the skateboard falling off the conveyor belt, but in the next scene it is on the conveyor belt and being crushed. (00:03:20)
Scrappy Doo: I'm as cute as a Powerpuff Girl. I'll get my own show.
Trivia: The voice of Scrappy was done by Scott Innes, who voices Scooby-Doo and others in the recent cartoons (since 1998).
Question: When the gang kicked Scrappy out, how did he get to Spooky Island and learn about the Daemon Ritus?
Answer: It's never explained. We're just left to assume he was somehow able to.
