Scooby-Doo is a franchise that we all know and love. It's helped to shape children's lives since it was first created in 1969, and the cartoon has undergone many different phases with a whole host of different people voicing the show's main characters, Fred, Daphne, Velma, Shaggy and, of course, Scooby. It was even made into a live-action movie in 2002!

Now the gang are returning to the big screen, this time in animated form. The movie will be called Scoob, and the cast has been chosen. It looks like this is going to be one re-make that no one should miss.

We can't wait!

The Mystery Inc. team are household names.

You know who they are... Fred is the leader of the group; Daphne knows karate (but is often kidnapped); Velma is the intelligent one (you can tell because she wears glasses), and Shaggy is usually scared... and hungry (us too). Shaggy and Scooby usually run away from danger, while the others try to solve the mysteries. We'd be with Shaggy and Scooby, we think!

"I would have gotten away with it, too, if it weren't for you meddling kids."

Although the show has been running for nearly half a century, the storyline does not tend to diverge much from the original formula. And that's what makes it so great! The team stumble across a mystery, which usually looks somewhat supernatural. They follow clues until they realize that it is actually a regular person trying to pull some sort of hoax. That's when they unmask them and hand them over to the authorities. Then the bad buy mumbles one of our favorite phrases in TV history!

Scooby-Doo comes from the world of Hanna-Barbera.

William Hanna and Joseph Barbera created many cartoons, starting way back in the fifties. They were the brains behind Tom and Jerry, The Flintstones, The Yogi Bear Show, The Smurfs, Wacky Races, and of course, Scooby-Doo, Where Are You! Now that it has become a member of the Warner Bros family, it has been decided that the gang should make a return to our screens.

Scooby-Doo has found himself on the big screen before.

In 2002, a live-action movie was made starring Freddie Prinze Jr as Fred, Sarah Michelle Gellar as Daphne, Linda Cardellini as Velma and Matthew Lillard as Shaggy. There was originally supposed to be three movies, but the 2004 sequel didn't do so great. There were two more movies released in 2009 and 2010, but these were released as TV movies rather than as big-screen productions. This new movie looks like it's shaping up to be far better already!

Did anyone used to watch Wacky Races ?

The movie is bringing in some characters from our other favorite franchises, too! The main villain in this movie will be Dick Dastardly, the notorious cheat in Wacky Races! Although, so far we don't know who will voice him. We're also waiting to see if his trusty side-kick, Muttley, will be alongside him. Who do you think would win in a head-to-head between Scooby and Muttley?

The cast of the new Scoob movie looks incredible.

Gina Rodriguez, who is the star of the hit CW show Jane the Virgin, will be taking on the role of clever-clogs, Velma. Meanwhile Will Forte, who was on Saturday Night Live for a decade, will be the voice of Shaggy. He's done a lot of cartoon voices before, including the Lego movies and the Cloudy with a Chance of Meatballs movies.

Some of the cast have worked together before.

Tracy Morgan will be playing Captain Caveman, who is another character from Hanna-Barbera. He was a character in Captain Caveman and the Teen Angels, in which a caveman thaws and solves mysteries in the present day. Tracy Morgan has also been on SNL, 30 Rock, and even starred in The Clapper, alongside Amanda Seyfried.

Amanda Seyfried was first known for her role in Mean Girls.

In 2004, when Seyfried was still a teenager, she landed the role of Karen in Tina Fey's Mean Girls. Acting alongside Rachel McAdams and Lindsay Lohan as the "stupid one", this was Seyfried's first movie, but it was definitely not her last.

Seyfried showed her musical side!

Seyfried got the role of Sophie in the ABBA extravaganza that is Mamma Mia!, which grossed over six-hundred million dollars worldwide. She reprized the role a decade later in Mamma Mia! Here We Go Again. Alongside many other movies, she also played Cosette in the Academy Award-nominated, Les Misérables. Now, she'll be starring as Daphne in Scoob. Hopefully, as this movie will probably be an updated version of the "Scooby" world, Daphne will be less of a damsel-in-distress, and the movie will, instead, focus more on her strengths.

She's not the only one with a musical background.

Zac Efron will be taking on the role of their peppy leader, Fred. He first came to fame through the beloved Disney movie, High School Musical. He has since also shown off his musical skills in both Hairspray and Greatest Showman. Will this Scooby-Doo re-make be turning into a musical, or is it just a coincidence?

Efron has been in a lot of light-hearted comedies.

It took a while for people to stop seeing Efron as another squeaky-clean Disney kid, but he has increasingly been in roles wherein he's been able to laugh at himself (and we've been laughing along with him!). His role in the two Bad Neighbours movies definitely helped him to cross-over into a different genre. And his role in Baywatch proved that his good looks didn't wane away when he stopped playing teen-heartthrob, Troy Bolton in 2008.

Efron has made it to Sundance Film Festival, too!

In a bit of a departure from his usual, light-hearted movies, Efron has taken on the role of notorious serial killer, Ted Bundy, in Extremely Wicked, Shockingly Evil and Vile. People have been very impressed with Efron's performance, but the main thing that's got people talking is his hair!

Have you ever seen the "panini" look irl?

Efron dyed his hair blond for his movie with Matthew McConnaughey, The Beach Bum. He then paired it with a darker beard, with lines cut into it... It certainly does resemble a panini... but is this the next big trend? Or is it just an Efron thing?

Will Efron and Seyfried will be paired as an on-screen couple?

Daphne and Fred always had a strange will-they-won't-they relationship in both the Scooby-Doo episodes and in the movies. Will they be together in this new movie? We hope so!

Are you excited for the new movie?

Scooby-Doo is a classic for a reason. From the psychedelic color-scheme, to the cries of "zoinks," "jinkies," and "jeepers," and, of course, the old howl of "scooby-dooby-dooooooo," this movie has a lot of history to fit in. And they'd better not miss anything! It looks like this movie is set to launch the franchise back into being a great success. The only problem is, we'll have to wait until 2020 to see it!
