Bad Export for You: The film originally received a 12 rating in the UK. It had to be cut down by about 3 minutes to get a PG.
Career Resurrection: This was the movie that managed to revive interest in the Scooby-Doo franchise after a period of no new material, leading to a long-running series of Direct-to-Video movies that is still going to this day.
Talking to Himself: Mark Hamill not only voices Snakebite Scrugs, but also Shaggy and Scooby's boss at the airport, the ghosts of Morgan Moonscar and the Confederate general, and a plantation worker.
What Could Have Been: Tara Strong says that she and the other voice actors were originally going to speak in Cajun accents. She herself says she found the accent very difficult and Jim Cummings (who is Cajun) said they didn't sound authentic, so they just went with typical Louisiana accents.
