What If...? (Seasons 1–3)

What If...? (2021) is Marvel Studios' animated anthology for Disney+, available to watch online on iFILM. Each episode grabs a familiar turn from the cinematic universe and asks one thing: what if it had gone the other way?

The guide through these parallel worlds is the Watcher, voiced by Jeffrey Wright. He observes, he never interferes — and there is plenty to observe. What if Peggy Carter took the super-soldier serum instead of Steve Rogers? What if T'Challa became Star-Lord? What if grief drove Doctor Strange to rewrite the laws of reality itself? The series pulls in voices from the original films, with Hayley Atwell, Sebastian Stan, Samuel L. Jackson and Benedict Cumberbatch stepping back into their roles.

Its painted, comic-panel animation lets the show do what the movies never could: kill off beloved heroes, snap timelines in half, and gather wildly different universes for one last fight. Stream every episode of What If...? online on iFILM.
