T'Nia Miller is reportedly cast as Jocasta in the upcoming Disney+ MCU series, Vision.
According to Deadline, Miller—known for her roles as Hannah Grose in The Haunting of Bly Manor, Victorine LaFourcade in The Fall of the House of Usher, and Zephyr Halima Ifa in Foundation—will take on a lead role opposite Paul Bettany's Vision.
Miller's Jocasta is characterized as cunning, powerful, and motivated by revenge. In Marvel comics, Ultron created Jocasta to be his companion. He attempted to upload the Wasp's consciousness into the android, but she alerted the Avengers, who subsequently removed it. After being reactivated by Ultron, Jocasta ultimately betrayed him, siding with the Avengers to ensure his defeat.

Last week, IGN reported that the WandaVision spin-off is being developed by a team of veteran Star Trek writers and producers. The series, which has been in development for over a year, previously confirmed the involvement of Star Trek: Picard writer and later showrunner Terry Matalas. Matalas will serve as showrunner for Vision Quest, reuniting with several other Star Trek writers in the process.

Marvel has not yet detailed the series' plot, though fans anticipate it will follow the fate of Paul Bettany's White Vision, last seen departing at the end of WandaVision. Deadline states the new series is set after WandaVision and will follow Vision's journey to regain his memory and humanity. Filming for Vision Quest began earlier this spring, primarily at Pinewood Studios in London, with additional location shooting spotted in Scotland.
Interestingly, the series is also expected to feature the return of James Spader's Ultron—last seen destroyed in 2015's Avengers: Age of Ultron—alongside the character Raza from the original Iron Man, who famously kidnapped Tony Stark.
Vision Quest is slated for release on Disney+ in 2026. This timeline suggests it will likely arrive before the delayed Avengers: Doomsday, though after Spider-Man: Brand New Day.
