Disney+ has called it Countdown to Avengers: Doomsday. The collection has fifteen entries: fourteen films and Loki, listed as a single series but present with both seasons. Adding up the runtimes cited by Inverse comes to 41 hours and 39 minutes, or roughly 42 hours. The two seasons of Loki alone account for 10 hours and 11 minutes — nearly a quarter of the entire programme.
The marathon begins before the Marvel Cinematic Universe even existed. The first two titles are X-Men from 2000 and X2 from 2003, both produced by Fox. They are followed by Captain America: The First Avenger, The Avengers, Avengers: Infinity War and Avengers: Endgame, which reconstruct the original team's history and its resort to time travel.
The more recent stretch includes Shang-Chi, Spider-Man: No Way Home, Black Panther: Wakanda Forever, Captain America: Brave New World, Deadpool & Wolverine, Doctor Strange in the Multiverse of Madness, Thunderbolts* and The Fantastic Four: First Steps. The selection holds together the new Avengers, the Fantastic Four, the X-Men and the collisions between parallel universes. Loki provides the temporal framework that connects most of these elements.
The omissions have drawn just as much attention. Left out of the playlist are WandaVision, Ant-Man and the Wasp: Quantumania, Avengers: Age of Ultron and Captain America: Civil War. Also missing is The Marvels, which ends with Monica Rambeau trapped in a reality inhabited by the X-Men — a scene that appeared to sit squarely in Doomsday's narrative territory.
Disney+ presents the collection as a countdown to the film, expected in cinemas on 18 December 2026. Even this abridged version of the saga takes up nearly two consecutive days without sleep.
