As the Marvel Cinematic Universe barrels toward its next epic team-up, Avengers: Doomsday, a surprising blast from the past is dominating streaming charts. Avengers: Age of Ultron, the 2015 sequel that divided fans and critics alike, has suddenly become one of the most-watched movies on Starz this July 2026. It's a testament to how anticipation for a new blockbuster can revive interest in earlier chapters.
With Avengers: Doomsday set to hit theaters on December 18—the same day as Dune: Part Three—the superhero fever is palpable across platforms like HBO Max and Disney+. But the ripple effect has now reached Starz, where Age of Ultron sits comfortably in the top ten streamed movies in the U.S. The film, which follows Earth's Mightiest Heroes as they battle the rogue AI Ultron (voiced by James Spader), originally earned a mixed reception for its darker tone and crowded plot. Yet, 11 years later, it's finding a new audience.
The timing couldn't be better. Avengers: Doomsday is already making headlines for its massive runtime—165 minutes, making it the second-longest MCU film ever—and its star-studded cast, which includes Tom Holland, Zendaya, and Jon Bernthal. These same actors are currently generating buzz for Christopher Nolan's The Odyssey, which opens this weekend. For fans craving more superhero action after that epic, Spider-Man: Brand New Day arrives on July 31, continuing the road to Doomsday.
But why is Age of Ultron suddenly so popular? Part of it is nostalgia, but a larger factor is the returning stars in Doomsday who first appeared in this sequel. Characters like Vision and Scarlet Witch, who debuted here, are set to play pivotal roles in the upcoming film. Fans are revisiting their origins, and the streaming numbers reflect that.
Financially, Age of Ultron was no slouch. Against a staggering $365 million budget, it grossed nearly $1.4 billion worldwide, making it the 19th highest-grossing film of all time at its release. While Doomsday is expected to surpass that, the question remains: can it top Endgame's $2.8 billion? Only time will tell, but the streaming surge suggests the appetite for Marvel's interconnected saga is as strong as ever.
For those who missed it the first time—or want to revisit the chaos—Avengers: Age of Ultron is currently streaming exclusively on Starz.
