And they would’ve gotten away with it, too, if it weren’t for… Dax Shepard?

Shepard is in negotiations to co-direct an animated Scooby-Doo movie for Warner Bros, EW has learned. Shepard and animation veteran Tony Cervone will helm the project from a screenplay written by Shepard and Matt Lieberman.

Scooby, Shaggy, Fred, Daphne, and Velma made their TV debut in Scooby-Doo, Where Are You! back in 1969, and Warner Bros. previously released the 2002 live-action Scooby-Doo and its 2004 sequel, both directed by Raja Gosnell and written by Guardians of the Galaxy’s James Gunn. Freddie Prinze Jr., Sarah Michelle Gellar, Linda Cardellini, and Matthew Lillard starred as the members of Mystery Inc., with Neil Fanning voicing Scooby.

Best known for his roles on shows like Parenthood and Robot Chicken, Shepard recently teamed up with Warner Bros. on the upcoming comedy CHiPs, which Shepard wrote, directed, and stars in.

The new Scooby-Doo will drive the Mystery Machine into theaters on Sept. 21, 2018.
