Avengers: Endgame, the 2019 film that concluded the first major saga of the Marvel Cinematic Universe, will be re-released in theaters beginning September 25, 2026. The re-release comes ahead of the December 2026 premiere of Avengers: Doomsday, likely serving both as a nostalgic reminder and a primer for audiences ahead of what promises to be one of the biggest MCU events yet.

Avengers: Doomsday, directed by the returning duo Joe Russo and Anthony Russo, is shaping up to be a massive ensemble film. It’s expected to bring together heroes from across the cinematic universe, including legacy Avengers, newer additions, and other major franchises under Marvel’s umbrella.

By re-releasing Endgame first, Marvel seems to be offering fans a cinematic “refresher,” a way to relive the stakes of the original saga before the next chapter unfolds. At the same time, the delay and strategic scheduling suggest the studio aims to give Doomsday the time and attention needed for its high ambitions.
