T'Nia Miller has reportedly been 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 one of the lead roles opposite Paul Bettany's Vision.
The character of Jocasta is described as "intelligent and formidable," with motivations driven by vengeance. In Marvel comics lore, Ultron created Jocasta to serve as his companion after uploading Wasp's consciousness into the android body. After alerting the Avengers to Ultron's plans, Jocasta ultimately betrayed her creator to help defeat him.

Recent reports indicate the WandaVision spin-off has assembled an experienced Star Trek writing team behind the scenes. The project, which has been quietly developing for over a year, has recruited Star Trek: Picard writer and showrunner Terry Matalas to helm Vision Quest - reuniting him with several fellow Star Trek alumni.

While Marvel Studios remains tight-lipped about plot details, speculation suggests the series will follow the story of Paul Bettany's White Vision, last seen departing at the conclusion of WandaVision. Deadline reports the show takes place after those events, chronicling Vision's quest to rediscover his memories and humanity. Production began earlier this year at Pinewood Studios in London, with additional filming occurring in Scotland.
The series is also rumored to feature returns of notable MCU characters including James Spader's Ultron (last appearing in Avengers: Age of Ultron) and Raza from the original Iron Man film.
Vision Quest is currently slated for a Disney+ release sometime in 2026, positioning it between Spider-Man: Brand New Day and the delayed Avengers: Doomsday in the MCU timeline.
