Marvel's "Vision Quest" casts Jocasta

T’Nia Miller has reportedly been cast as Jocasta in Marvel's upcoming Disney+ series Vision, marking her entry into the MCU.

Deadline confirms Miller - known for her roles in The Haunting of Bly Manor, The Fall of the House of Usher, and Foundation - will star opposite Paul Bettany's Vision as one of the show's leads.

The character description reveals Miller's Jocasta as "cunning and powerful" with motivations driven by revenge. In Marvel comics lore, Jocasta was originally created by Ultron as a synthetic companion. After having Wasp's consciousness briefly uploaded into her framework, she ultimately turned against her creator to help the Avengers.

The project brings together veteran Star Trek talent behind the scenes, with Star Trek: Picard showrunner Terry Matalas leading the creative team. Production began earlier this spring at London's Pinewood Studios, with some location shooting occurring in Scotland.

While Marvel Studios remains tight-lipped about plot details, the series will reportedly explore Vision's quest to reclaim his memories and humanity following the events of WandaVision. Sources indicate the story may involve surprise returns, including James Spader's Ultron and Raza from Iron Man's origin story.

Scheduled for a 2026 Disney+ release, Vision Quest will arrive after Spider-Man: Brand New Day but before the delayed Avengers: Doomsday.
