I suppose this is both a fun fact and Scooby "news," as this was just revealed last week.
The original cut of the Scooby-Doo live action movie was far different than what the final version of the movie ended up being. In a shocking Facebook post by movie director James Gunn, the writer revealed on the movie's 15th anniversary that the first Scooby-Doo live action film was originally to be rated R with several edgy scenes, including some featuring the female stars (Linda Cardellini and Sarah Michelle Gellar) wearing very low-cut outfits. In addition, through a bit more digging around on this, it seems Velma's character was going to completely redone so she was a completely
different character than the brainy, nerdy girl we know and love today. One of these character revisions included Velma lusting over Daphne and a make-out scene between the two characters. Another scene would have had Daphne being frightened and convincing Fred to have her stay in his hotel room, which led to the two of them having sex. In the end, the MPAA board denied all of these controversial scenes and essentially told the filmmakers they would have to drop the aforementioned controversies unless they wanted an R-rated movie. Before the movie's release, James Gunn wrote a new script which edited out all the sexually promiscuous content, which is the version we all know today.

In Scooby-Doo and the Monster of Mexico, there are several inaccuracies regarding the Spanish culture throughout the movie. They are:
Though certainly not a "fun" fact, Lorena Gale, who played the librarian in Scooby-Doo! The Mystery Begins tragically passed away due to throat cancer during the last stages of production of the movie, making The Mystery Begins her final film role ever.
Trudy from Scooby-Doo! Camp Scare is likely based off of Raven from the original Teen Titans series. In addition, both Raven and Trudy are voiced by the same person, Tara Strong.
While it's commonly known that The New Scooby-Doo Mysteries intro (more specifically the monsters dancing) was based off of Michael Jackson's "Thriller", it's less known that "Thriller" included uncredited vocals by Vincent Price, who would less than a year later join the Scooby-Doo franchise to voice Vincent Van Ghoul in The 13 Ghosts of Scooby-Doo.

Jane Wiedlin, who voices Dusk, is also part of a very famous pop group, The Go-Gos. They are most known for their hits "We Got The Beat" and "Vacation." The group had seven songs reach the Billboard Hot 100, giving them significant fame.
In the end credits for The Scooby-Doo Show, if you look closely, you can see the letters "HB" (standing for Hanna-Barbera) patterned across the background.
Though the Scrappy-Doo shorts made between 1980-1982 are often referred to as "the 7-minute shorts," they are actually closer to six minutes. On average, each of these shorts were about six minutes and 29 seconds long.
Both Flim-Flam (from the 13 Ghosts of Scooby-Doo) and Sybella (from Scooby-Doo and the Ghoul School) are voiced by the same voice actress, Susan Blu.
