What If...? is an American animated anthology television series created by A. C. Bradley for the streaming service Disney+ based on the Marvel Comics series of the same name. It is the fourth television series in the Marvel Cinematic Universe (MCU) produced by Marvel Studios, and the studio's first animated series from Marvel Studios Animation. The series explores alternate timelines in the multiverse that show what would happen if major moments from the MCU films occurred differently. Bradley serves as head writer for the first two seasons, with Matthew Chauncey for the third, and Bryan Andrews as the lead director.
Jeffrey Wright stars as the Watcher, who narrates each episode of What If...?
The series features a cel-shaded animation style, with character likenesses based on the actors from the films such as Hayley Atwell for Captain Carter. During the writing of the first season, Captain Carter emerged as a prominent character who would go on to appear in each subsequent season.
What If, sometimes stylized as What If…?, is a comic book anthology series published by Marvel Comics whose stories explore how the Marvel Universe might have unfolded if key moments in its history had not occurred as they did in mainstream continuity. Since What If debuted in 1977, the comics have been published in 14 series as well as occasional stand-alone issues. In 2024, Marvel announced that What If…? would expand to include alternate explorations of continuity within other non-Marvel Universe properties owned by their parent company The Walt Disney Company from its fifteenth volume onwards, beginning with Aliens: What If…?, based on the Alien franchise.
