British actor T’Nia Miller has been confirmed to play Jocasta in Marvel Television’s Disney+ series now simply titled “Vision,” an eight-episode follow-up to WandaVision that is filming at Pinewood Studios for a 2026 debut. The casting places Miller opposite Paul Bettany’s White Vision and the returning voice of James Spader as Ultron, while highlighting Marvel’s shift to a showrunner-led model under Star Trek: Picard alum Terry Matalas.
Marvel Studios has quietly filled a pivotal slot in its WandaVision sequel by hiring T’Nia Miller (Foundation, The Fall of the House of Usher) to portray Jocasta, the sophisticated AI traditionally built by Ultron as his “bride.” Deadline’s scoop, echoed by multiple trade sites, describes the live-action Jocasta as “cunning, powerful and driven by revenge,” signalling that the android may enter the story as an antagonist before her comic-book turn toward heroism.
Miller joins a cast led by Paul Bettany, with James Spader reprising Ultron alongside Todd Stashwick, Faran Tahir and newcomer Ruaridh Mollica. Principal photography began in March under the working title Tin Man at Pinewood Studios, giving the production a long runway to meet its Disney+ Phase Six slot in 2026.
Showrunner Terry Matalas—brought in when Marvel abandoned its head-writer system—says the narrative “follows that [White] Vision’s journey” immediately after his Westview escape and has been a “wonderful creative experience… on a very big stage.” His writers’ room includes Battlestar Galactica veteran Michael Taylor and several Picard alumni, a team Matalas calls “a thousand ways to do exactly that” log line Marvel handed him.
Disney’s May upfront confirmed the shortened title Vision and positioned the series in a slimmed-down Marvel slate that executives say emphasises “quality over quantity” after audience fatigue with earlier Disney+ output.
In comics lore Jocasta—created by Ultron from the Wasp’s brain patterns—ultimately rebels against her maker to join the Avengers, a redemptive arc fans expect the series to mine. Her arrival, coupled with Ultron’s return, reopens thematic fault lines about autonomy and identity first explored in Age of Ultron and WandaVision, suggesting Vision will tackle both unresolved family drama and the MCU’s evolving relationship with artificial intelligence.
