“As they race to stop this global ‘dogpocalypse,’ the gang discovers that Scooby has a secret legacy and an epic destiny greater than anyone imagined.”

In the cast is Will Forte as Shaggy, Gina Rodriguez as Velma, Zac Efron as Fred and Amanda Seyfried as Daphne.

As well as them, Harry Potter star Jason Isaacs plays Dick Dastardly, and Mark Wahlberg plays Blue Falcon, who recruits the gang to help him.

Along with them, Kiersey Clemons, Ken Jeong, Tracy Morgan and Billy West play supporting characters, all of which will be familiar to fans from other Hanna-Barbera cartoons.

A surprise cameo comes from Simon Cowell, who plays himself, while his son Eric is the voice of Ben.
