Marvel just can’t do anything small — and Avengers: Doomsday is proving that in the most epic way possible. If insider reports are to be believed, the upcoming Phase Six blockbuster is set to shatter the MCU’s all-time runtime record, clocking in at a jaw-dropping 3 hours and 45 minutes — blowing past even Avengers: Endgame.

Why Is It So Long?
Simply put — Doomsday has a mountain to climb. Insider Nexus Point News first reported the 3 hours 45 minutes figure, while other reliable scoopers have placed the current cut at around 3 hours. Either way, this is shaping up to be the longest Marvel movie ever made.
The record was previously held by Avengers: Endgame with a runtime of 3 hours and 1 minute CBR — and Doomsday is expected to leave that far behind.

The reasons are actually very logical. The film is juggling over 30 confirmed cast members spanning the Avengers, X-Men, Fantastic Four, and the New Avengers. It also faces the massive challenge of introducing Doctor Doom as a credible villain from scratch — unlike Thanos, who had years of MCU buildup. Add in a multiverse-hopping narrative and it’s easy to see why nearly four hours makes sense.
According to Wikipedia’s article on Avengers: Doomsday, early box office tracking reported by Variety in March 2026 described it as “strong,” with the film predicted to be 2026’s highest-grossing release. Wikipedia
Star Power That Justifies Every Minute
The cast alone reads like a who’s who of cinema royalty — Robert Downey Jr. as Doctor Doom, Chris Hemsworth, Pedro Pascal, Chris Evans, Patrick Stewart, Ian McKellen, Tom Hiddleston, Anthony Mackie, and Florence Pugh among dozens more. Giving each character meaningful screen time naturally demands more runtime, and fans are largely here for it.
