If you want to know more about What If...?, we’ve rounded up all the information we know. You can also check out all the Marvel shows and films that are on Disney Plus right now.

When does What If...? air?

What If...? is currently slated for a summer 2021 release. There’s no specific air date yet, but EW did release an article that cited an August release. 

This is further backed up by an Italian Disney Plus press release (via badtaste.it), which stated that the show will land on the platform on Friday, 6 August 2021. Marvel HQ has yet to officially confirm this, however. 

The show will run for ten episodes, which we assume will be released on a weekly basis.

Watch the trailer

On the Disney Plus Investor Day, a full trailer was dropped for the series. You can watch this below:

Who are the cast and crew?

Whilst the show will be animated, there will be a number of Marvel actors reprising their roles for this series.

Those confirmed to voice act include Robert Downey Jr., Michael B. Jordan, Sebastian Stan, Josh Brolin, Mark Ruffalo, Tom Hiddleston, Samuel L. Jackson, Chris Hemsworth, Haley Atwell, Chadwick Boseman, Karen Gillan, Jeremy Renner, Paul Rudd and Michael Douglas. Jeffrey Wright will also act as the narrator – also known as the Watcher.

The show is being written by A.C. Bradley and is directed by Bryan Andrews. The animation has been co-developed by Marvel Studios and Squeeze, with Stephan Franck serving as head of animation.

What If...? plot

What If...? is an anthology series, so every episode will stand as its own story. The character narrating throughout will be Uatu, the Watcher, an extra-terrestrial being who plays out alternative timelines within the multiverse to see how the stories end.

The trailer confirmed that the following scenarios will be played out:

  • What if Peggy Carter got the super-soldier serum and became Captain Britain?
  • What if Prince T'Challa was picked up by Yondu and became Star Lord, rather than Peter Quill?

We don’t yet have confirmation on what the other stories will be, however, we saw one shot of Loki in a seemingly powerful position – so perhaps this could be an alternative universe where the God of Mischief was successful in the Battle of New York, and wasn't defeated by the Avengers.

There’s a rather frightening shot of a zombie Captain America facing off against Bucky Barnes. Perhaps this is a universe where Hydra reign supreme and turn Captain America into an undead super soldier?

There’s also a scene of Doctor Strange facing off against an evil clone of himself. If we had to guess, this could tie in with the multiverse theory being introduced in the sequel film.

There were also clips of other famous avengers such as Iron Man, Captain Marvel and Thor – but beyond knowing that they appear, we can’t yet guess what the plots will be about.
