Scooby-Doo! Secret Covert Organization of Otherworldly Beings

Scooby-Doo! Secret Covert Organization of Otherworldly Beings is a 2021 American computer-animated supernatural mystery comedy film produced by Warner Animation Group and based on Hanna-Barbera's Scooby-Doo franchise. The film is directed by Tony Cervone from a screenplay by Adam Sztykiel, Jack Donaldson, Derek Elliott, and Matt Lieberman, and a story by Lieberman, Eyal Podell, and Jonathon E. Stewart. It stars the voices of Frank Welker as the titular character (the only member of the original cast to participate), as well as Matthew Lillard, Kate Micucci, Zac Efron, and Grey DeLisle as Shaggy, Velma, Fred and Daphne respectively, with Mark Wahlberg, Jason Isaacs, Kiersey Clemons, Ken Jeong and Tracy Morgan as other Hanna-Barbera animated characters. The film is a reboot of the Scooby-Doo film series, and it is intended to be the first installment in the Hanna-Barbera Cinematic Universe. The film's story follows the formation of Mystery Incorporated, and how they are then joined by Dynomutt and Blue Falcon to solve their most challenging mystery related to the origin and the true purpose of their own mascot in conjunction with Dick Dastardly's plot to unleash Cerberus, a monstrous three-headed ghost dog, upon the world.
Plans for a new Scooby-Doo theatrical film began in July 2014, when Warner Bros. announced that they would reboot the Scooby-Doo film series with an animated film. Cervone was hired to direct the film in August 2015, with Dax Shepard being brought to co-direct it in September 2016. By October 2018, Shepard was no longer a part of the project. Much of the cast was hired in March 2019, while animation services were provided by Reel FX Animation Studios. Scooby-Doo! Secret Covert Organization of Otherworldly Beings was originally set for a worldwide theatrical release on August 15, 2021, by Warner Bros. Pictures, making it the third theatrical film to feature the Scooby-Doo characters, after Scooby-Doo in 2002 and Scooby-Doo 2: Monsters Unleashed in 2004.
== Plot ==
A young and lonely Shaggy Rogers befriends and adopts a talking stray dog, whom he names Scooby-Dooby-Doo. On Halloween night, Scooby-Doo and Shaggy meet three young detectives named, Fred Jones, Daphne Blake, and Velma Dinkley, before venturing into a haunted house. Inside, the kids encounter a ghost, whom they capture and unmask as costumed thief Mr. Rigby. Inspired by the experience, they decide to form a group, Mystery Inc., to solve mysteries together.
Ten years later, Mystery Inc. goes into business, Tom and Jerry visit Mystery Inc. with entrepreneur Simon Cowell as their investor, but Shaggy, Scooby, Tom and Jerry are excluded as Cowell refuses to do business with them, forcing them to quit Mystery Inc. as the gang feel disheartened. Later that night, Shaggy, Scooby, Tom and Jerry are attacked at a bowling alley and chased by small robots called Rottens. The pair are rescued by Dee Dee Skyes, Dynomutt, and the masked superhero, Blue Falcon. The Rottens are then revealed to belong to supercriminal Dick Dastardly who wants to capture Scooby as part of a plan involving the mystery behind the three skulls of Cerberus.
Meanwhile, Fred, Daphne, and Velma discover that Shaggy, Scooby, Tom and Jerry are with Blue Falcon before Dastardly is revealed to be Officer Jaffe in disguise and then imprisons them. Escaping with the help of one of the Rottens, they make contact with Dee Dee via Dynomutt. Velma explains that she and the others are being taken to Messick Mountain, where the last skull is located. The group then finds out Dastardly's plan is to open the gates to the Underworld in order to rescue his dog Muttley, who was trapped during an attempt to steal the Underworld's riches, and Dastardly needs Scooby-Doo because only he can unlock the gates.
Blue Falcon, Scooby, Tom, Jerry, Dee Dee, and Dynomutt arrive at Messick Mountain and head underground to a hidden Mesozoic island. There they find the last skull being guarded by Captain Caveman. Following a short battle, Fred and Shaggy arrive, but Fred is revealed to be Dastardly in disguise as he steals the last skull. The Rottens then throw the real Fred, Daphne, and Velma out of his airship and Dastardly destroys the Falcon Fury. Dastardly then captures Scooby, Tom and Jerry and takes them to Athens. Fred and Blue Falcon argue while Velma, Daphne, Dee Dee, and Dynomutt try to break them up, but Shaggy stops their argument and takes the blame for Scooby's capture after letting his jealousy strain their friendship. After Shaggy gives an inspiring speech, everyone works together to reconstruct the Mystery Machine in order to pursue Dastardly.
Arriving in Athens, Dastardly uses the three skulls to reveal the gate to the Underworld and attempts to use Scooby's paw to open it, only to be interrupted by Scooby's friends in a flying Mystery Machine. The Rottens shoot them down while Dastardly releases Cerberus; unaware that Dynomutt landed them safely. As Scooby, Dastardly, and the civilians flee from the rampaging Cerberus, Scooby, Tom and Jerry runs to the crash site and reunites with their friends while Dastardly reunites with Muttley in the Underworld and they escape after stealing some of Alexander the Great's treasure. While determining how to trap Cerberus, Velma discovers more of the mystery behind Scooby's ancestry and its connection to the Underworld. With help from the Rottens, Mystery Inc. and friends trap Cerberus and put him back in the Underworld. However, Shaggy sacrifices himself to lock the gate. The gang realizes that there is another exit, which Scooby unlocks, and Shaggy is reunited with them.
The Rottens turn on Dastardly and Muttley, and Shaggy unmasks Dastardly who is revealed to be Simon Cowell in disguise. Upon realizing why it doesn't make sense, Velma unmasks Cowell who is revealed to be Dastardly in disguise the whole time trying to demoralize the gang and break the team up. Dick Dastardly and Muttley are both taken into custody by Blue Falcon, Dynomutt, and Dee Dee, and are arrested.
Back home at Venice Beach, the gang unveils their new Mystery Inc. headquarters and celebrates with Blue Falcon, Dynomutt, and Dee Dee, who in turn give the gang an upgraded Mystery Machine before Scooby and the gang head off to solve another regular mystery together again.
During the credits, the Mystery Gang's popularity rises and they are seen consulting Dr. Benton Quest after leaving the Rottens in his care, Blue Falcon and Dynomutt form the Falcon Force with new members Captain Caveman, Jabberjaw, Atom Ant, and Grape Ape while Muttley breaks Dastardly out of prison.
