Behind the scenes

 * Scooby says "Ruh-roh" twice.
 * Velma says "Jinkies" thrice.
 * Shaggy says "Zoinks" once.
 * The Mystery Machine's vanity plate is "GROOVY." When the Mystery Machine is rebuilt, Trevor changes it to "GLOOMY."
 * The unmaskings of old villains are shown from the Scooby-Doo, Where Are You! episodes "Spooky Space Kook," "A Clue for Scooby-Doo," "Bedlam in the Big Top," and "What a Night for a Knight."
 * This is the first piece of Scooby-Doo media that shows Velma as a lesbian, although there had already been an implication of it in the TV series Scooby-Doo! Mystery Incorporated, and James Gunn had intended her to be one in his draft for the live-action film Scooby-Doo.
 * The song during the opening credits is set to the tune of the theme song to the original TV series Scooby-Doo, Where Are You!
 * The guy at the grocery looks similar to the Ghost of Mr. Hyde from the Scooby-Doo, Where Are You! episode "Nowhere to Hyde."
 * The person outside the Scary Witch Shakes is dressed like the witch from the Scooby-Doo, Where Are You! episode "Which Witch is Which?"
 * Coco has drawings of the Creeper and the Space Kook on her cell walls.
 * The gang looks into Nefario's book the way they looked into a nondescript book in the Where Are You! episode "What a Night for a Knight."
 * Banana Split's Ice Cream Hour is a reference to the band The Banana Splits and their show, The Banana Splits Adventure Hour.
 * Yogi's Yoga is a reference to Yogi Bear.
 * Coco makes a joke about Goths 'R Us, which is a reference to the toy store Toys 'R Us.
 * When Scooby and Shaggy come to the rescue of their friends, Scooby breaks the fourth wall by referring to the fact the franchise is named after him.
 * After the inmates escape, Warden Collins breaks the fourth wall by telling the gang they don't have to worry because they're in a family movie.
 * Special thanks are given to Joe Ruby and Ken Spears, who had nothing to do with this movie, but did create the original series, Scooby-Doo, Where Are You!

Errors

 * The 10,000 Volt Ghost already happened, so it's odd how it's being redone as if it never happened before.
 * Fred implies that their first case happened in "What a Night for a Knight," when he said in that very same episode after discovering the abandoned suit of armor, "Well, gang, it looks like we're up to our armor plates in another mystery."
 * It's implied that Charlie was a costume worn by Sarah Jenkins, even though it was a real robot she had sabotaged.
 * The gang has connected all the villains' disguises to have been made by Coco even though some of the villains were known to have made their own costumes. It also funnily enough conflicts with Scooby-Doo! Team-Up #3, in which it was revealed that all the bad guys had been buying their costumes from a warehouse in Gotham City.
 * The gang carry around a red and off color white Scooby Snacks box, and this is sold at the grocery, but a window of the grocery advertises Scooby Snacks with a green and blue-green box.
 * When Fred tells Daphne to open up the guestbook, she opens it up in the middle. Maybe it does take rocket science.

Marketing and promotion
The movie was screened at New York Comic Con on October 7, 2022.

Everlasting influence

 * On the October 8, 2022 episode of Saturday Night Live, it was referred to by Colin Jost during the Weekend Update segment.
