Marvel Studios released its official Phase 6 cast confirmation list overnight — locking in the rosters for Avengers: Doomsday (December 18, 2026) and VisionQuest (October 14, 2026). The official confirmation comes nine weeks before San Diego Comic-Con 2026 (July 23-26) — earlier than any previous Marvel franchise reveal.
Marvel Studios chairman Kevin Feige confirmed the Phase 6 cast lockdowns in a livestream presentation overnight. The reveals confirm what trade reports have been speculating for months — Avengers: Doomsday will feature the largest ensemble in MCU history.
Avengers: Doomsday final cast: Robert Downey Jr. (Doctor Doom), Chris Hemsworth (Thor), Tom Hiddleston (Loki), Pedro Pascal (Mister Fantastic), Vanessa Kirby (Invisible Woman), Joseph Quinn (Human Torch), Ebon Moss-Bachrach (The Thing), Ian McKellen (Magneto), Patrick Stewart (Professor X), Kelsey Grammer (Beast), Anthony Mackie (Captain America/Sam Wilson), Sebastian Stan (Bucky Barnes), Letitia Wright (Shuri), Tom Holland (Spider-Man), Charlie Cox (Daredevil), Florence Pugh (Yelena Belova), Wyatt Russell (US Agent), Lewis Pullman (Sentry), Simu Liu (Shang-Chi), Hailee Steinfeld (Hawkeye / Kate Bishop), and approximately 18 additional confirmed names.
VisionQuest final cast: Paul Bettany (Vision), James Spader (Ultron, returning from Age of Ultron (2015)), James D'Arcy (J.A.R.V.I.S., returning from Agent Carter), Todd Stashwick (Paladin, the bounty hunter), plus expanded supporting cast featuring multiple Westview-residents from WandaVision (2021). The October 14 Disney+ premiere will be the first MCU Disney+ series to feature a fully-multiversal continuity arc.
The strategic timing. Marvel's cast confirmation nine weeks before SDCC is unprecedented — previous Phase reveals were held until the convention itself for maximum hype-effect. This lockdown signals Marvel's confidence in the slate's commercial reception; the studio no longer needs the SDCC stage for cast reveals because the audience is already locked in. Industry observers interpret this as Marvel's strongest pre-release stance in over five years.
What's missing from the Doomsday confirmation: Robert Downey Jr. is listed only as Doctor Doom (not Iron Man); Chris Evans is not confirmed; Mark Ruffalo / Hulk is conspicuously absent; Brie Larson / Captain Marvel is not confirmed. These absences are consistent with the film's reported plot premise (the Multiverse Saga's incursion event has erased these characters from the timeline). The absences will be the most-discussed marketing element through SDCC.
