"Scooby! is back with its favorite Scooby Snack-eating Great Dane and his mystery-solving friends in an all-new animated feature film adventure. Here's everything you need to know about your next chance to see this mystery machine in action.

We're Where's Scooby-Doo, which premiered on CBS in 1969 and was first introduced to Scooby and the gang in 1969. Since then, numerous animated shows have aired on ABC, The CW and Cartoon Network, the most recent of which was Scooby-Doo and Guess Who, which premiered last June on the Cartoon Network app Boomerang?

The live-action Scooby-Doo sequel, Scooby-Doo 2: Monsters Unleashed, was the last time the Scooby project was released theatrically. But now, 16 years later, Scooby brings the whole gang back for their very first animated Scooby feature to hit theaters with the puppies themselves.

Scooby features a stellar cast, most of whom have never voice acted in a Scooby Doo series or movie before. Zac Efron ("High School Musical") as Fred Jones, Amanda Seyfried ("Mean Girls") as Daphne Blake, Gina Rodriguez ("Jane the Virgin") as Velma Dinkley, Shaggy Rogers Will Forte ("The Last Man on Earth"), and original cast member Frank Welker as Scooby-Doo.

There are also cameo appearances by other classic heroes and villains in Hanna-Barbera, though not yet seen in the trailers or photos. Voice talent includes Tracy Morgan (30 Rock) as Captain Caveman, Kiersey Clemons (Dope) as Dee Dee Sykes, Ken Chong (Community) as dog wonder Dynomutt, Jason Isaacs as Dick Dastardly ( Harry Potter) and Mark Wahlberg (Boogie Nights) as Blue Falcon.

Scooby tells the story of the Mystery Gang's first encounter, focusing on the relationship between BFF Scooby and Shaggy. Since that fateful meeting on the beach several years ago, the two have solved countless mysteries together with the help of their friends Daphne, Fred, and Velma.

Flashbacks to the characters' origins color the new central mystery: To avert a "dogpocalypse," the gang must foil a plot to unleash Cerberus, a terrifying ghost dog. Although unconfirmed, there is no doubt that Dick Dastardly, played by Isaac, is involved in this nefarious plot. Whatever happens, this will surely be the biggest case yet and will reveal the ultimate fate of the Scoobies.

The film is directed by Tony Servon, who has been working in animation for over 25 years. He is no stranger to Hanna-Barbera, as he has directed several Tom and Jerry shorts as well as the Scooby-Doo projects Scooby-Doo!And Kiss: Rock and Roll Mystery and Scooby-Doo!Abracadabra! -Doo. Kelly Fremon Craig ("The Edge of Seventeen") wrote the script based on a story by Matt Lieberman ("The Addams Family" in 2019).

Reel FX Animation Studios, known for last year's "UglyDolls" and 2014's "The Book of Life," has written the cute and stylish "Scoob!"

The Marvel Cinematic Universe, or MCU, is currently comprised of 23 interrelated Marvel films. But get ready for the HBCU (Hanna-Barbera Cinematic Universe). Yes: Scoob!" is the first in a series of Hanna-Barbera animated classics, including "The Flintstones," "The Jetsons," and "Wacky Races," to be revived on the big screen.

As such, "Scooby! ' ticket sales and reception are going well, we should see more of our favorite childhood friends in the years to come.
