With Warners currently at work on a new big-screen animated Scooby-Doo movie, now comes word on who’ll be lending their vocals to Fred Jones and Daphne Blake.

Courtesy of Variety, Zac Efron has signed on to voice Fred and Amanda Seyfried will be voicing Daphne. The duo join a cast that currently includes Will Forte as Shaggy, Gina Rodriguez as Velma Dinkley and Tracy Morgan as Dick Dastardly.

Titled Scoob, the animated offering will focus on the famed Mystery Machine guys, gals and hound as they team with other Hanna-Barbera characters to save the universe from the nefarious Dick Dastardly. Space Jam’s Tony Cervone is on directing duties, with a script from The Addams Family’s Matt Lieberman.

At this stage, Scoob is booked in for a May 2020 release.
