Overview
- All four short teasers rolled out in theaters ahead of Avatar: Fire & Ash before official online posts, completing a staggered, theater‑first campaign.
- The videos accumulated about 1.02 billion combined views, with record platform totals on Instagram and TikTok and social activity far above typical Marvel drops.
- Marvel posted a thank‑you video and launched an official countdown to the December 18, 2026 release as the studio highlighted success without showing Robert Downey Jr.’s Doctor Doom.
- The clips confirm key on‑screen returns and crossovers, including Chris Evans as Steve Rogers, Thor, legacy X‑Men (Patrick Stewart, Ian McKellen, James Marsden), Wakandan and Talokan leaders, and The Thing.
- Joe and Anthony Russo described the teasers as narrative information and clues, while a widely discussed fan theory linking their countdown numbers to Avengers: Endgame timestamps remains unconfirmed.
