Marvel's "What If...?" - Who's returning to voice their character, and who isn't

The MCU's What If...? series that will debut and air on Disney+ next Wednesday (August 11th) is based on the Marvel Comics series of the same name. The comic book run debuted in February of 1977 and had a total of 13 volumes by March of 2019. Even with it's on and off publication streak, fans still have a lot of fun with these stories. The main premise of What If...? is simply asking that question. What if certain events in Marvel history happened differently? What if these titular moments had not occurred in mainstream continuity? With an endless possibility of outcomes, and the multiverse officially canon, the What If...? series can be a fun addition to the MCU.
With the series being animated it would be easy for Marvel to create multiple seasons. In fact, a second season has been unofficially confirmed. This season, we will see a lot of our favorite MCU characters in very unlikely situations. Because of that, there are a lot of our favorite MCU actors/actresses returning to lend their voice to their Marvel animated counterpart. But unfortunately, there are just as many who have decided not to return - or according to Guardian of the Galaxy, Dave Bautista, some actors may have never been asked at all. With that being said, let's dive into the cast of Marvel's What If...? on Disney+.

It's unclear why only a number amount of MCU talent is returning to their roles for the animated series, but it can be assumed it was all due to contractual obligation/un-obligation. Some actors may have also simply decided not to return, or according to Dave Bautista, not even asked. If what Bautista says is true, it could just be that Marvel did not want to create a new contract for actors who already have plans to fulfill their appearance amount they already signed for. Drumming up a new contract, which can be very expensive depending on the talent, can just be inefficient in more ways than one. Although not all of the true MCU cast is returning, we still get just as many who are. Keep in mind that all of these characters listed are only just the confirmed cast. If we know Marvel, we know that there are many surprises to come.
