- The Cast Showoff: Josh Keaton gets to show off his singing chops in the movie's two songs. Frank Welker and Kate Micucci also show this in the second song.
- He Also Did:
- This is the third Scooby Doo film that Ethan Spaulding directed, after Scooby-Doo! Legend of the Phantosaur and Scooby-Doo! Camp Scare. He also worked on Avatar: The Last Airbender, Justice League Action, Batman: Assault on Arkham, and Justice League: Throne of Atlantis.
- Co-writer Emily Brundige worked on Star vs. the Forces of Evil, The Power Puff Girls 2016, and Home: Adventures with Tip & Oh.
- The Other Darrin: In the original cartoon, Dr. Najib was voiced by Vic Perren. This movie has him voiced by Iqbal Theba.
- Playing Against Type: Josh Keaton and Natalie Lander voice Chad and Chrissy Holdout, characters who are considerably meaner and more narcissistic than their usual nice guy type characters. The fact they also masqueraded as ghost pirates adds to that. This is especially notable for Josh given that Tommie is much closer to his usual character types.
- Talking to Himself: Quite a bit to go around:
- As usual, Frank Welker voices Fred and Scooby.
- Grey DeLisle Griffin voices Daphne, Laura Holdout, and Bingo Belle.
- Jeff Bennett voices the museum guide and the deputy.
- Josh Keaton voices Chad Holdout and Tommie.
- Kevin Michael Richardson voices Captain Bash and the sheriff.
