Marvel Casts T’Nia Miller as Jocasta in 'Vision Quest': Everything You Need to Know

Marvel Studios is expanding its Disney+ slate, and fans of WandaVision have a new reason to celebrate. Acclaimed British actress T’Nia Miller, known for her powerful performances in The Fall of the House of Usher and The Haunting of Bly Manor, has officially joined the cast of Vision Quest, the highly anticipated Vision-centric spin-off series. This exciting news marks another strategic move by Marvel to deepen its storytelling and broaden its character base within the Marvel Cinematic Universe (MCU).

T’Nia Miller is a versatile and dynamic actress with a growing fan base, thanks to standout performances in hit Netflix series such as The Fall of the House of Usher, Years and Years, and The Haunting of Bly Manor. Her ability to portray complex characters with emotional depth has made her a favorite among genre fans and critics alike.

Now, Miller is bringing her talents to the Marvel Cinematic Universe in a significant role that could reshape the future of synthetic characters in the MCU.

Vision Quest is a new Disney+ miniseries focused on Vision, the beloved android played by Paul Bettany. The series is a direct follow-up to the events of WandaVision and aims to explore Vision's search for identity, purpose, and perhaps even a soul, following the loss of his memories and Wanda.

Helmed by Terry Matalas, known for 12 Monkeys and Star Trek: Picard, Vision Quest is part of Marvel’s Phase Six and is expected to debut in 2026. Fans can also look forward to the return of James Spader as Ultron, creating a thrilling dynamic as past and present threats collide.

T’Nia Miller is set to play Jocasta, a character with deep comic book roots. In the Marvel Comics, Jocasta is an android originally created by Ultron to be his bride, but she ultimately rebels against him and allies herself with the Avengers. Known for her intelligence, strength, and struggle for autonomy, Jocasta is a compelling figure—and an ideal fit for Miller’s acting range.

Her role promises to bring layered emotional storytelling and philosophical exploration of artificial intelligence, identity, and what it means to be “alive.” Given Miller's acting credentials, fans can expect a nuanced performance that adds both gravitas and humanity to the Vision Quest narrative.

Marvel’s casting choices have often been strategic, bringing in talented actors who elevate the storytelling and connect with diverse global audiences. Miller’s casting is no different. Her presence brings not only representation but also the potential for rich character development that deepens the MCU's exploration of androids and AI.

Her role as Jocasta could potentially spin off into other Marvel stories, offering opportunities for crossovers, character alliances, or even stand-alone arcs.

With T’Nia Miller joining the cast of Vision Quest as the formidable Jocasta, Marvel fans have a lot to look forward to. Her inclusion signals that Vision Quest won’t just be another superhero show—it’ll be a thoughtful, character-driven expansion of the MCU’s synthetic saga.

Expect compelling performances, philosophical dilemmas, and the potential return of iconic villains like Ultron. As Marvel continues to evolve, T’Nia Miller’s Jocasta could very well become a fan-favorite and an essential part of the future Marvel storylines.

Stay tuned to Disney+ for more updates, and get ready to dive back into the world of Vision when Vision Quest premieres in 2026.
