The trailer for the highly anticipated series What If…? was released online late last week. This release comes a day after the latest episode of Loki and before the release of the new Black Widow movie. The trailer, running just over two minutes, was posted on the official Marvel Twitter page, and within 24 hours, it received 4.5 million views, proving fans are eager to learn more about the upcoming release.

The animated series, which explores multiple different scenarios from the Marvel Cinematic Universe, had thousands of tweets reacting to the different segments and hypothesizing about the contents of each episode, as well as the story it references. An episode list was found by devoted fans and tweeted out shortly after.

A common theme picked up by multiple people is that because of a T'Chala focused episode, this upcoming series will be Chadwick Boseman's official last work done for the MCU.

The last piece of excitement came from the inclusion of Spider-Man in a Disney+ property because the character has previously been off the table due to contract talks between Sony and Marvel for the movie and TV rights to the character.
