According to IMDb, Mckenna Grace has officially been cast as Daphne Blake in an upcoming live-action Scooby-Doo series, with a first look image already making the rounds online.
Mystery Inc. Has Its Daphne — Now What?
This is a genuinely exciting piece of casting news for anyone who grew up with Mystery Inc. Grace has built a remarkable resume playing emotionally complex young women — from Ghostbusters: Afterlife to The Handmaid's Tale to Gifted — and there's real range there that could bring something fresh to Daphne beyond the classic "pretty one" archetype. But one confirmed casting also means four major roles are still wide open. Fred, Velma, Shaggy, and the Great Dane himself are all presumably up for grabs, and that's where things get really interesting for fans.
The remaining Mystery Inc. slots are some of the most iconic roles in animation history, which means the fancasting conversation is going to be loud. Velma in particular has become a culturally charged character in recent years, making her casting choice especially high-stakes. Fred needs someone who can play earnest and slightly oblivious with genuine charm. And Shaggy — arguably the hardest role to get right in live-action — demands an actor who can be genuinely funny without tipping into parody.
What myCast Fans Are Already Saying
The myCast community has been dreaming up Scooby-Doo ensembles for a while now, and the results across multiple fan stories are a fascinating snapshot of where the fandom's head is at.
Over on the Scooby-Doo story — the most expansive with 69 roles mapped out — fans have tapped Dacre Montgomery for Fred Jones, which honestly makes a lot of sense. Montgomery has the jawline, the leading-man energy, and enough self-awareness from his Stranger Things days to avoid making Fred a cardboard hero. For Velma, Auliʻi Cravalho is the fan pick, a choice that feels both fresh and earned — Cravalho has serious dramatic chops and a natural warmth that could make Velma's know-it-all tendencies endearing rather than grating. Noah Jupe gets the nod for Shaggy, which is an intriguing swing — he's more of a dramatic actor by reputation, but that unpredictability could be exactly what Shaggy needs. Notably, fans here had picked for Daphne before the Grace announcement, so it'll be interesting to see how the community recalibrates.
