In Mike Flanagan we trust. The horror auteur is adapting Stephen King’s Carrie for the small screen.

Her mother’s domineering influence leads to a “horrific, bloody incident,” from which there is no turning back. The cast and crew took SDCC by storm for a fun-filled panel, surprising fans with the show’s official teaser and premiere date.

The miniseries stars a mix of Flanagan favorites and newbies for the filmmaker, including Summer H. Howell, Samantha Sloyan, Siena Agudong, Alison Thornton, Joel Oulette, Josie Totah, Arthur Conti, Thalia Dudek, Amber Midthunder, and Matthew Lillard.

Marvel Studios Casting Announcements and Premiere Dates

• VisionQuest Premiere Date: October 14, 2026

It’s all quite marvelous, isn’t it? Of course I saved the best for last. Marvel Studios brought more than doom to Hall H at SDCC. Attendees watched exclusive footage from Avengers: Doomsday, but the rest of the world learned more about what’s on the horizon for the MCU. For starters, VisionQuest, the upcoming miniseries starring Paul Bettany as Vision, will premiere on Oct. 14, 2026.

Ryan Gosling will also headline a new Ghost Rider film as the title motorcycle-riding hero, which Shawn Levy will direct. The movie will hit theaters in 2028. Additionally, Hayley Atwell will reprise her fan-favorite role as Peggy Carter in Doomsday, and I can’t wait to watch her inevitable scenes with Chris Evans’ Steve Rogers.

In a bombshell announcement, David Jonsson, who fans might know from The Long Walk and Industry, will take up the Black Panther mantle in Black Panther 3 alongside Letitia Wright’s Shuri. Jonsson will step into the role of the late T’Challa’s son, who was introduced as a child in Black Panther: Wakanda Forever. Ryan Coogler will return to direct, with the third film debuting in theaters on Dec. 15, 2028. Winston Duke will also return as M’Baku.
