According to
/Film, Marvel is in the process of developing a
What If animated anthology series for Disney+. Apparently, the show will be overseen by Kevin Feige but will not be in canon with the Marvel Cinematic Universe - and if you're familiar with the comics, you'll know why.
What If will re-imagine certain key moments and scenarios in Marvel history to see how things might have played out if some significant detail had been altered. For example, What If What if Thanos joined the Avengers?, or What if Professor X had become Juggernaut?
We don't which, if any, of the existing comic stories the series will adapt, but “What if Loki had found the hammer of Thor?” is expected to be covered.
The report speculates that some MCU actors might reprise their roles for
What If, but no other solid details are provided. More info should come our way soon, either at the upcoming Investors Meeting on April 11, or at San Diego Comic-Con in July.
