T’Nia Miller Joins Marvel’s VISION Series as Jocasta, a Vengeful AI with a Complicated Past

Marvel Studios is continuing to expand the WandaVision legacy with its upcoming Disney+ spinoff Vision, and we now know one of the most intriguing additions to the cast, The Fall of the House of Usher standout T’Nia Miller has signed on to play Jocasta.

According to Deadline, Miller is believed to be one of the series' leads, starring opposite Paul Bettany, who returns as the synthezoid Vision.

The show is expected to pick up after the events of WandaVision, with Vision on a journey to piece together his fractured memory and rediscover what it means to be human.

Miller’s character, Jocasta, comes with deep Marvel lore. Originally introduced in 1977’s Avengers #162, Jocasta was created by Ultron as a robotic companion modeled on the brain patterns of Janet Van Dyne (aka the Wasp).

In the comics, Jocasta ultimately rebels against her programming and sides with the Avengers, later struggling with her own identity and even attempting to become more human.

The casting breakdown for the series described Jocasta as “cunning, powerful, determined, and motivated by revenge.” That lines up with her comic book roots, though the revenge angle raises questions. Is she still Ultron’s creation in the MCU? Or does Vision offer a completely new take?

The inclusion of James Spader in the cast, reprising his role as Ultron, adds even more weight to this storyline. Could this series give us a long-overdue reunion, or reckoning between Vision and his homicidal "father"? Also joining the cast are Todd Stashwick, Ruaridh Mollica, and Faran Tahir, who returns as Raza from the original Iron Man.

This marks the second spinoff to emerge from WandaVision, following Agatha All Along, which stars Kathryn Hahn. With Daredevil: Born Again also underway, Marvel’s Disney+ slate continues to build its roster of character-focused, lore-deep series.

While we still don’t have an official release date, the cast and concept alone make Vision one of the more interesting Marvel projects on the horizon.
