Trivia: Scooby-Doo on Zombie Island
- Hey, It's That Voice!: Frank Welker reprises his role of Fred Jones, and is the only pre-A Pup Named Scooby-Doo voice actor in the cast.
- In Memoriam: To Don Messick, the original voice actor for Scooby-Doo who had passed away the previous year, just before recording began.
- Keep Circulating the Tapes: The two Skycycle songs were never properly released (a hokey synthesized version appeared on the soundtrack for Scooby-Doo! and the Witch's Ghost). Better make friends with someone who knows how to mix out sound effects and dialogue!
- The Other Darrin: Scooby, Shaggy, Daphne, and Velma all have new voice actors (Shaggy is voiced by Billy West, and Velma's actress had previously provided vocals for a Johnny Bravo/Scooby-Doo crossover).
- Recycled Script: The concept was originally a unfinished SWAT Kats episode, "The Curse of Kataluna" (which would've involved a Succubus). Suddenly, the Darker and Edgier tone makes a lot more sense. (Parts of it were also recycled by the writer, Glenn Leopold, for a season two ep, "Eclipse", of Jonny Quest: The Real Adventures.)
