T’Nia Miller is reportedly joining the Marvel Cinematic Universe in a major role as Jocasta in the upcoming Disney+ series centered on Vision. Known for her standout performances in *The Haunting of Bly Manor*, *The Fall of the House of Usher*, and *Foundation*, Miller is set to portray one of the central characters opposite Paul Bettany’s Vision.
In the Marvel comics, Jocasta is a highly intelligent and powerful figure originally created by Ultron to serve as his ideal mate. Designed using the consciousness of the Wasp, she ultimately rebelled against Ultron and sided with the Avengers to stop his destructive plans. Her onscreen portrayal is expected to reflect her complexity—described as “cunning and powerful,” with a strong personal motivation rooted in revenge.
This casting news arrives as production on the series, now officially titled *Vision Quest*, gains momentum. According to recent reports, the show is being developed by a team of seasoned *Star Trek* writers, including Terry Matalas, who previously served as showrunner for *Star Trek: Picard*. The series has been quietly in development for over a year and is now actively filming, primarily at Pinewood Studios in London, with recent location work also spotted in Scotland.
The storyline remains under wraps, but it’s said to follow Vision as he embarks on a journey to reclaim his lost memories and rediscover his sense of humanity. This takes place after the events of *WandaVision*, where White Vision was last seen flying away into the unknown. The series aims to explore the emotional and existential journey of a synthetic being caught between identity and purpose.
Excitingly, the show is also rumored to bring back James Spader as Ultron, the villainous AI previously destroyed in *Avengers: Age of Ultron*, and reintroduce Raza, the terrorist from the original *Iron Man* who played a pivotal role in Tony Stark’s origin story. These developments hint at a deep narrative with strong thematic ties to the MCU’s past and future.
*Vision Quest* is scheduled to debut on Disney+ in 2026, positioning it to potentially arrive before *Avengers: Doomsday*, though after *Spider-Man: Brand New Day*. With its unique blend of sci-fi, drama, and superhero action, the series promises to be a standout addition to the MCU’s Phase 6 lineup.
