Before joining the Mystery Inc. gang, Daphne Blake and Velma Dinkley have an origin story of their own to journey through; at least that’s the plot of a new feature-length film. The live action movie will follow teens Daphne and Velma as they work to solve a mystery fit for the future investigators. According to Deadline, Shades of Blue’s Sarah Jeffrey has been cast as Daphne, and Last Man Standing star Sarah Gilman is set to bring the quirky and intelligent Velma to life. Warner Bros. Home Entertainment will release the feature in 2018.

Daphne and Velma is being produced in conjunction with Ashley and Jennifer Tisdale’s Blondie Girl Productions and Blue Ribbon Content. The latter may be familiar to fans of CW Seed’s Vixen and the impending release of Constantine’s animated series. Daphne and Velma’s synopsis is as follows:

“Before their eventual team-up with Scooby and the gang, bright and optimistic Daphne and whip-smart and analytical Velma are both mystery-solving teens who are best friends but have only met online — until now. Daphne has just transferred to Velma’s school, Ridge Valley High, a tech-savvy institute with all the latest gadgets provided by the school’s benefactor, tech billionaire Tobias Bloom. And while competition is fierce among the students for a coveted internship at Bloom Innovative, Daphne and Velma dig beyond all the gadgets and tech to investigate what is causing some of the brightest students in school to disappear — only to emerge again in a zombie-fied state.”

In a statement concerning the announcement, Peter Girardi, Blue Ribbon’s EVP, addresses a desire to explore new stories and perspectives in the world of Scooby-Doo:

“We wanted to give the audience a new take on these two familiar faces, who are fan favorites in the Scooby-Doo universe. Daphne and Velma are two iconic and strong female characters, and this latest adventure of theirs will be both inspiring and entertaining for the audience.”
