Zac Efron and Amanda Seyfried have joined the cast of the new animated Scooby-Doo film. The film, titled Scooby, is set to be directed by Tony Cervone from a script by Matt Lieberman. The two stars join Will Forte, Gina Rodriguez, Tracy Morgan and Frank Welker in the project.

Forte will lend voice to the iconic character of Shaggy, the best friend of Scooby-Doo, who will be voiced by Welker in the animated feature. Rodriguez will take on the role of Velma, the brains of the group known as Mystery Inc, while Morgan will voice star as Captain Caveman, a character who has appeared in other Hanna Barbera cartoons, but not the original "Scooby-Doo".
