A recent fun fact post talked about how "Scooby on Ice!" from Scooby-Doo and Guess Who? was not the first time that Tara Lipinski has done voice work for Scooby-Doo. Unbeknownst to most, she also voiced Grey in the What's New, Scooby-Doo? episode "Camp Comeoniwannascareya." This inspired me to do a deep dive project on all the guest stars from The New Scooby-Doo Movies and Scooby-Doo and Guess Who? to discover if any of them had previously had roles as other characters on the show (and I was surprised to discover quite a few of them did!). This post highlights all the guest stars from these two series that have had previous roles in other episodes before or after their first appearance in the franchise. I included both real-life celebrities and voices of fictional characters, such as The Addams Family and Wonder Woman; however, I did not include ones that were extremely famous voice actors (for example, Casey Kasem plays Alexander of Josie and the Pussycats, so it's obvious he's had other roles in the show).

Janet Waldo, most famous for voicing Jane Jetson, played both Grandmama Addams and Josie in The New Scooby-Doo Movies. However, she would later voice several notable characters in The Scooby-Doo Show, including Scooby-Dee from "The Chiller Diller Movie Thriller," Lisa Vanaugh from "Vampire Bats and Scaredy Cats," and Arlene Wilcox from "To Switch a Witch."

We probably all know that Don Knotts would go on to voice the groundskeeper in the video game, Scooby-Doo! Night of 100 Frights.

Jackie Joseph, who voiced Melody, went on to voice a very random Scooby-Doo character almost 20 years later...Velma's Aunt Thelma from "Scooby Dude."

This one is perhaps more well-known, but Tim Conway would later go on to voice Fred's dad, Skip Jones, in Scooby-Doo! Pirates Ahoy. He also voiced Professor Alexander Graham in the Scooby-Doo! Night of 100 Frights video game.

Moving on to the Guess Who guest stars, Rachel Kimsey voiced Wonder Woman. Later in the series, she'd also voice Marla and the chef from "A Fashion Nightmare!"

If you thought Sandy Duncan and Cher were the only guest stars to have roles in both The New Scooby-Doo Movies and Guess Who, you would be wrong! Mark Hamill appeared as as himself in Guess Who, but he had previously voiced one of Jeannie's masters, Corey Anders, in "Mystery in Persia" of The New Scooby-Doo Movies. Mark Hamill previously voiced Snakebite Scruggs in Scooby-Doo on Zombie Island; Steve in Scooby-Doo and the Alien Invaders; Shifty in Night of the Living Doo; Deacon, Babyface Boretti and the store owner in Scooby-Doo! Camp Scare; and Zip Elvin in Scooby-Doo! Moon Monster Madness. Mark Hamill has also provided several voices of the side characters and villains in What's New Scooby-Doo?, Scooby-Doo! Mystery Incorporated and Be Cool, Scooby-Doo!. His What's New roles include Captain Guzman and Emperor Caesar Salidicus in "Pompeii and Circumstance," as well as Tommy's father in "A Scooby-Doo Christmas." He voiced Crybaby Clown and the Drill Sargeant from "The Night the Clown Cried" and "The Night the Clown Cried II: Tears of Doom" in SDMI, in addition to voicing General Stall in Be Cool, Scooby-Doo's "Area 51 Adjacent." Moreover, in Guess Who, he also voiced The Joker in "What a Night, for a Dark Knight!" and the Trickster in "One Minute Mysteries!".

In addition to appearing as himself in Guess Who, George Takei also appeared as the White Wizard and Mr. Wang in SDMI. The Old Samurai in Scooby-Doo and Samurai Sword was also voiced by Takei.

Malcolm McDowell had previously voiced the Sly Baron in Scooby-Doo! Moon Monster Madness in 2015 before appearing in the first season of Guess Who.

Ending right where we began, Tara Lipinski voiced Grey in "Camp Comeoniwannascareya" from What's New, Scooby-Doo?.

I hope you enjoyed reading this article and learned something new about some of the guest stars! I'm treating this as a running list, and will update this post as guest stars from either of these shows make voice appearances in other episodes.

There's a lot of Scooby content out there that entered production, but was ultimately never shown to the world. From an official Scooby film fully animated in anime style to a movie that would have essentially been the result of mashing-up two DTV ideas into one, there's so much Scooby content we could have seen but never got to. Many of these ideas aren't necessarily common knowledge, so I wanted to highlight all of them in this post. The scope of this article only covers projects that were started and never completed, not existing projects that were significantly reworked (such as SCOOB! for example, which, fun fact, was originally going to be written by Be Cool writer Jon Colton Barry). I'm approaching this article as a new project that is a work-of-progress, rather than a finalized post. If there's any Scooby content that you're aware of that was officially confirmed to have entered development that I don't have here, please feel free to let me know and provide a link to a reliable source where you saw the info!

Of course, we have to start with all the original versions of the show that Scooby could have been. The first of these was House of Mystery, which was heavily based on The Archie Show, which was popular at the time. The series would have featured Geoff, Mike, Kelly, Linda, and Linda's brother W.W., along with their dog Too Much, who played the bongo drums. Collectively, they made up the band Mysteries Five. Too Much was a large sheepdog, intended to have a resemblance to the Archies' dog Hot Dog. However, this was rejected because it was felt to be a ripoff of Marmaduke, and it was changed to a Great Dane. Later on, the show was changed to be more based on The Many Loves of Dobie Gillis as opposed to The Archie Show. The title of the show was changed to Mysteries Five, the name of the teenagers' band. There was later one more title change to Who's S-S-Scared? after the kids' names were changed to reflect what we know them to be know: Fred, Daphne, Velma, Shaggy and Scooby. However, the show was rejected by CBS president Fred Stanton due to being too scary for young viewers. Thus, as we know, after some revisions the show was changed into what we now know as Scooby-Doo, Where Are You?.

A multi-universe series called Hanna-Barbera Babies was once pitched by Iwao Takamoto after the success of A Pup Named Scooby-Doo in 1991, but was ultimately never picked up.

A young Hex Girls spinoff in 2000 was pitched but was never picked up. Above is an image of Thorn that would have been in the show.

Scott Jeralds apparently pitched a series featuring Scooby's son according to an interview with the Unmasked Scooby-Doo Podcast, but it was declined in favor of What's New, Scooby-Doo?.

A third movie in the Gunn live action film series was reportedly being written by Dan Forman and Paul Forley. However, the film was cancelled due to Scooby-Doo 2: Monsters Unleashed not performing as well as hoped. James Gunn tweeted the plot in 2020, which was the gang going to Scotland to rid a town of monsters, but they discover the monsters are actually the victims. 

On a similar note, Brian Levant, who made the 2009 and 2010 live action films, said in an interview that if there would have been a third film, it would have been titled Scooby-Doo's Zany Time Travelin' Christmas Adventure. Another idea Levant had for a film revolved around Irish fairy tales.

The resumé of art director Ted Blackman informs us that Scooby-Doo! Music of the Vampire and Big Top Scooby-Doo were originally one movie, titled Scooby-Doo and the Circus of Vampires. Presumably, this was changed due to it being too similar to the 1972 horror film Vampire Circus​ and the plot was divided into two films.

In an interview, the voice of Velma from Scooby-Doo Adventures: The Mystery Map, Stephanie D'Abruzzo, mentioned that she believed the puppet film was meant to be a pilot for a potential series, but the series never entered development.

Jon Colton Barry has shared that he originally planned to write an episode of Be Cool, Scooby-Doo! featuring the Hex Girls. In addition, the Halloween episode was originally supposed to feature Scrappy. However, the episode was scrapped because WB wanted to do two 11-minute shorts instead. Apparently, according to the article The Hex Girls, How a Fictional Rock Band Become Cult, Queer, Girl Power Icons, Rick Copp also gets called from time to time about a Hex Girls spinoff that never took off.

On January 6, 2022, character designer Tracy Mark Lee revealed on his Instagram page that there was originally going to be episodes of Scooby-Doo and Guess Who? featuring Mel Brooks and Dolly Parton. He also shared that Stephen Silver had drawn character designs for Dolly and Mel, posting Dolly's on that same day. A few weeks later, on January 25, 2022, Tracy posted Mel's design on his Instagram account as well. The episode ideas were never used, because both celebrities politely declined the roles.

In addition, according to a Scoobypedia interview with Chris Bailey, an episode featuring Michael Phelps and Jabberjaw, and a King Kong parody with Grape Ape were also considered. Presumably, the Grape Ape/King Kong episode would have been "The Lost Mines of Kilimanjaro!".

A follow-up to SCOOB! titled Scoob! Holiday Haunt was announced on December 22, 2021 by Tony Cervone on Instagram, after previously being hinted in an interview in June. The film was set to be directed by Michael Kurinsky and Bill Haller, written by Tony Cervone and Paul Dini, and produced by Tony Cervone and Mitchell Ferm. The cast who voiced the young gang in the original SCOOB! (Frank Welker, Iain Armitage, Ariana Greenblatt, McKenna Grace, and Pierce Gagnon) were all set to reprise their roles. Mark Hamill, Cristo Fernandez, Michael McKean, Andre Braugher, and Ming-Na Wen also were a part of the cast. A test screening for the film occurred in April, and we also got a first look at the film on April 6, 2022. However, on August 2, 2022, after production had nearly been finished, the film was suddenly cancelled due to a shakeup in WB leadership with the Discovery merged. The new CEO of Warner Discovery, David Zaslav, cancelled the film citing his desire to move WB towards a more cost-effective theatrical model of films, and citing that he felt streaming projects were not as profitable. The film was still screened to the cast and crew, according to Iain Armitage on Instagram. The film was completed on November 5, 2022. On December 31, 2023, the design of the villain, which would have been Krampus, was posted on Instagram. Here is what would have been the description for the film:

To celebrate Scooby Doo's first Christmas, 10-year-old Shaggy and the gang take him to a holiday-themed resort owned by Fred's favorite Uncle Ned. When the park is beset by a ghostly haunting, the kids must solve a 40-year-old mystery to save the resort and show Scooby the true meaning of Christmas.

In November 2022, an Amazon listing revealed a possible new Scooby film titled Scooby-Doo and the Haunted High Rise. However, in an interview, the director stated that it was cancelled due to tax write-offs. Another interview from the same channel also confirmed there was a potential Teen Titans Go! crossover in the works.

On May 23, 2022, it was announced that a new series, Scooby-Doo and the Mystery Pups, would air on the Cartoonito block of HBO Max. The series was set to center around Shaggy and Scooby serving as camp counselors for three puppies, whom they teach their mystery solving skills to. The three puppies appeared to be stand-ins for Velma, Fred and Daphne. However, on March 3, 2023, one of the show's writers Roger Eschbacher announced that the show had lost its distribution rights with HBO Max, meaning that it is cancelled.

Hi everyone!

With all the discussion lately following Curse of the 13th Ghost about what's canon and what's not, SDF and I have been working on a project about what could be considered canon. In our definition, canon means that there are no continuity errors with other things in the Scooby-Doo franchise that would prevent it from being in the main continuity. Anything that is not canon would be discontinuous with another incarnation, or it somehow contradicts another Scooby-Doo episode, special, or film.

The following is the canon we came up with. Some non-canon movies fit together nicely with others, such as the LEGO or live action films, and have been placed in a canon together. All incarnations under the "separate canons" category are all in their own, individual canons and do not fit together with anything else in the franchise. Some notes are provided where our placement might be a bit confusing. However, if there's anything you feel should be placed elsewhere, please let us know in the comments and we'll be happy to explain our reasoning as to why we chose to place it there.

The Flash Canon
The Flash Canon represents any episodes that appeared in a clip montage from "The High School Wolfman's Musical Lament." Because The Flash captured the same monsters that the gang had already captured in Scooby-Doo, Where Are You?, "One Minute Mysteries" happened in an alternate canon. Because this episode appeared in the clip montage, this means any other episode that had a clip appear in that montage is also in this canon.

Scooby-Doo and Guess Who?
1. Revenge of the Swamp Monster!
2. Peebles' Pet Shop of Terrible Terrors!
3. The Scooby of a Thousand Faces!

​Scooby-Doo! The Sword and the Scoob (a flashback from Be Cool, Scooby-Doo! is shown; Daphne makes a comment that Fred's dad is mean, which is likely a nod to Scooby-Doo! Mystery Incorporated since Fred's dad is nice in Pirates Ahoy; Daphne also keeps her quirky personality from Happy Halloween)
