VisionQuest's first public trailer is set to debut at San Diego Comic-Con 2026 (July 23-26), with Marvel Studios reportedly building a Hall H presentation around the WandaVision-trilogy closer. Paul Bettany's Vision returns October 14 to Disney+ alongside James Spader's surprise Ultron reprise.
Marvel Studios' streaming-TV slate for late 2026 is shaping up around two flagship releases: VisionQuest (October 14, 2026) and the long-anticipated Avengers: Doomsday (December 18, 2026). The pre-release marketing campaigns for both are now converging on San Diego Comic-Con 2026 (July 23-26), with VisionQuest's first public trailer reportedly debuting there.
The first-look footage was previewed at Disney's 2026 Upfront presentation in May, with attendees confirming the series carries a notably darker, more philosophical register than WandaVision. Showrunner Terry Matalas — coming off the universally-acclaimed third season of Star Trek: Picard — has explicitly framed VisionQuest as a meditation on identity and consciousness rather than a conventional superhero series.
The plot premise: Paul Bettany's Vision — reconstructed from the White Vision body teased at the end of WandaVision (2021) — undertakes a metaphysical quest to recover his memories, his sense of self, and ultimately his place in the post-Wanda MCU. The series is reportedly the closing chapter of what Marvel internally calls "the WandaVision trilogy" — alongside WandaVision (2021) and Agatha All Along (2024).
James Spader's Ultron return is the trailer's most-marketed reveal. Spader voiced Ultron in Avengers: Age of Ultron (2015) and has not reprised the role since. His return — exact narrative role still carefully held — represents one of the MCU's longest-pending character resurrections. James D'Arcy reprises his role as Edwin Jarvis (the AI consciousness from Agent Carter from which Vision's neural patterns derive), bridging multiple Marvel TV continuity branches.
