One Bold Change Just Made Mike Flanagan’s Upcoming Stephen King Series Even Better
Mike Flanagan is reuniting with a frequent collaborator for his next Stephen King series, a fan-pleasing move landing amid a fresh King surge—from HBO Max’s acclaimed IT prequel to Glen Powell’s The Running Man stumbling at the box office.
Stephen King adaptations are everywhere right now, for better and worse. Glen Powell’s The Running Man redo face-planted at the box office, but over on Max, the IT prequel Welcome to Derry is already locked for season 2 and pulling in raves. Sliding right into that moment: Mike Flanagan is in the home stretch on a new take on King’s first novel, and he’s bringing his MVP back with him.
Flanagan’s Carrie is coming to Prime, and yes, Kate Siegel is in
Prime Video ’s Carrie is a limited series aiming for 2026, making it the third on-screen version of King’s 1974 debut — the one told through letters, reports, and clippings — about a sheltered, bullied girl who unleashes hell at prom. Brian De Palma ’s 1976 film still slaps. The 2013 remake, less so. That’s why the headline here is Flanagan reuniting with Kate Siegel, his most frequent collaborator and, not coincidentally, his real-life wife.
Why this pairing matters (and the numbers back it up)
Flanagan and Siegel have been a package deal in one way or another since Oculus hit in 2013 — a $44 million sleeper that basically launched his mainstream run. Since then, Siegel has popped up all over his work: Netflix ’s The Haunting of Hill House and The Haunting of Bly Manor, the small-town sermon turned nightmare that was Midnight Mass, and the gothic victory lap The Fall of the House of Usher. On the feature side, she’s in Ouija: Origin of Evil, Gerald’s Game, and Flanagan’s recent The Life of Chuck. She also co-wrote the home-invasion nasty Hush with him, and in 2024 she directed a segment of the anthology V/H/S: Beyond from a script Flanagan wrote. Carrie will mark collaboration number ten for the two of them.
If you like data points: the projects where Siegel is in the mix tend to be Flanagan’s best-reviewed. Meanwhile, his three lowest-rated since Oculus — the fairy-tale-tilted Before I Wake (2014), the pricey Shining sequel Doctor Sleep (2019), and the YA-leaning The Midnight Club (2022) — are also the only ones from that period that didn’t involve Siegel. Correlation isn’t causation, but it’s hard to ignore the pattern.
The cast is a sweet spot of regulars and fresh faces
Alongside Siegel, Flanagan is pulling in some familiar ringers. Samantha Sloyan — the unforgettable villain of Midnight Mass — is back, as is Rahul Kohli, who’s been a standout in multiple Flanagan projects. Newer to his orbit: Matthew Lillard (coming off a supporting turn in The Life of Chuck), Prey breakout Amber Midthunder, and Heather Graham. It’s a lineup that feels exactly like what you want from a Flanagan show — his core players plus a few curveballs that make you sit up.
Big picture for King die-hards
Between Welcome to Derry’s momentum and this new Carrie getting the full Flanagan treatment, it’s a strong stretch for King on TV. And while it’ll be tough for any 2026 horror series to outshine the current buzz around Pennywise ’s origin story, Flanagan plus Siegel is as reliable as it gets. If you’ve been waiting for a Carrie that honors the book’s epistolary bite without feeling like a nostalgia retread, this one just moved to the top of the watchlist.
