The female members of Mystery Inc. are getting their own origins movie. Warner Bros. Television Group’s digital studio, Blue Ribbon Content, has begun production on Daphne and Velma, a live-action feature-length film focusing on the teenage Scooby-Doo duo.

The pic stars Sarah Jeffery (Shades of Blue) as the scarf-sporting redhead Daphne Blake and Sarah Gilman (Last Man Standing) as the freckled and bespectacled Velma Dinkley. Hailing from Ashley Tisdale and Jennifer Tisdale’s Blondie Girl Productions, Daphne and Velma will be released by Warner Bros. Home Entertainment next year.

Here’s the logline: 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.

“Blondie Girl is committed to telling stories from a female perspective, and we could not be more thrilled to give Daphne and Velma their own story,” said the Tisdale sisters, who are producers and founders of Blondie Girl Productions. “It’s so exciting to partner with Warner Home Entertainment and Blue Ribbon Content to introduce a new generation to the smart, charismatic, fearless females that we all know and love.”

Said Peter Girardi, EVP of Blue Ribbon Content & EVP Alternative Programming at Warner Bros. Animation: “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.”

Daphne and Velma is produced by Blue Ribbon Content and Blondie Girl Productions with Production Services provided by Lifeboat Productions. Ashley Tisdale, Jennifer Tisdale, Amy Kim, Jaime Burke and Suzi Yoonessi serve as producers, with Yoonessi also directing from a script written by Kyle Mack & Caitlin Meares.
