T’Nia Miller is set to portray Jocasta in the upcoming Disney+ MCU series Vision.
According to Deadline, Miller, known for roles in The Haunting of Bly Manor as Hannah Grose, The Fall of the House of Usher as Victorine LaFourcade, and Foundation as Zephyr Halima Ifa, will star alongside Paul Bettany’s Vision.
Miller’s Jocasta is characterized as “shrewd and formidable,” motivated by vengeance. In Marvel comics, Ultron created Jocasta as a potential partner, transferring Wasp’s consciousness into the robot. Wasp informed the Avengers, who removed her consciousness. Later reactivated by Ultron, Jocasta turned against him and allied with the Avengers to defeat him.

IGN reported last week that the WandaVision spin-off is being crafted by a team of experienced Star Trek writers and producers. The series, in development for over a year, will be led by Terry Matalas, previously a writer and showrunner for Star Trek: Picard, who will serve as showrunner for Vision Quest, collaborating with several Star Trek writers.

Marvel has not yet disclosed the series’ plot, but fans speculate it will explore the journey of Paul Bettany’s White Vision, last seen departing in WandaVision. Deadline notes the series follows Vision post-WandaVision, focusing on his quest to reclaim his memory and humanity. Filming began this spring at Pinewood Studios in London, with additional location shooting in Scotland.
Interestingly, the series is expected to feature the return of James Spader as Ultron, last seen defeated in 2015’s Avengers: Age of Ultron, and Raza from the original Iron Man, who held Tony Stark captive in a cave.
Vision Quest is slated for a Disney+ release in 2026, likely arriving before the postponed Avengers: Doomsday but after Spider-Man: Brand New Day.
