T’Nia Miller is reportedly set to portray 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 version of Jocasta is characterized as cunning, powerful, and motivated by revenge. In the Marvel comics, Jocasta was created by Ultron to be his companion. Ultron uploaded the Wasp's consciousness into the robotic body, but the Wasp alerted the Avengers, who subsequently removed it. After being reactivated by Ultron, Jocasta ultimately betrayed him and sided with the Avengers to bring about his defeat.

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

Marvel has not yet revealed the series' plot, though fans anticipate it will explore the fate of Paul Bettany's White Vision, who was last seen flying away at the conclusion of WandaVision. Deadline stated the new series takes place after WandaVision and follows Vision's journey to recover his memory and humanity. Filming for Vision Quest commenced earlier this spring, primarily at Pinewood Studios in London, with some location shooting also reported in Scotland.
Interestingly, the series is also expected to feature the return of James Spader's Ultron, who was last seen being destroyed in 2015's Avengers: Age of Ultron, and the character Raza from the original Iron Man, who was responsible for kidnapping Tony Stark.
Vision Quest is scheduled for release on Disney+ sometime in 2026. For those tracking the MCU timeline, this means the series will likely premiere before the delayed Avengers: Doomsday, although it is expected to arrive after Spider-Man: Brand New Day.
