If Marvel's WandaVision , The Falcon and the Winter Soldier , and Loki on Disney+ weren't enough for 2021, Marvel Studios is changing it up yet again with a brand-new series titled What If...?

As Marvel Studios' first animated series, What If...? explores the MCU stories fans know but if certain details had been changed from Black Panther 's Killmonger saving Tony Stark in the original Iron Man to Peggy Carter taking the super-soldier serum instead of Steve Rogers.

While the premise is rich with storytelling potential, What If...? looks to bear more relevance to the greater MCU than fans originally thought following the multiversal implications of Loki .

In addition, a huge number of MCU stars returned to voice their characters for the series, and it's a lot more than fans originally thought!

Even though a majority of the MCU roster has returned to voice their characters for the series, the same can't be said for everyone.

In addition to Robert Downey Jr., Chris Evans, and Brie Larson having their character's voices provided by other voice actors, Peter Parker's Tom Holland and Natasha Romanoff's Scarlett Johansson have joined the ranks of those sitting this series out.

Also, while previous reports claimed voice actors would be used for Benicio Del Toro and Benedict Cumberbatch as The Collector and Doctor Strange respectively, Marvel Studios now credits Del Toro and Cumberbatch for their performances confirming that they did, in fact, return for the series.

Having 50+ actors, many of which who are household names, reprising their roles for a single project is a tremendous feat and lends credence to What If...? having a major impact on the MCU going forward.

New confirmed actors such as Vision's Paul Bettany and the Wasp's Evangeline Lilly are interesting since Bettany recently appeared in WandaVision and Lilly is set to star in 2023's Ant-Man and the Wasp: Quantumania which recently begin filming .

In addition, Marvel fans are sure to appreciate Happy Hogan and Iron Man director Jon Favreau at the mic along with Andy Serkis as Ulysses Klau and Clark Gregg as Agent Phil Coulson .

Now the absence of Chris Evans and Robert Downey Jr. isn't all that surprising considering what it would cost to bring them back and the nature of their contracts, but the most glaring omissions are that of Brie Larson and Scarlett Johansson.

Brie Larson is set to star in 2022's The Marvels , a sequel to her 2019's Captain Marvel film. It's possible that scheduling conflicts or perhaps the nature of her contract is responsible but nothing has been confirmed.

Like Chris Evans and Robert Downey Jr., Scarlett Johansson's absence would've been chalked up her time in the MCU having concluded now that Black Widow has been released.

However, her decision to sue Disney over the terms of Black Widow 's release has muddied the waters and may lead to additional speculation behind her nonparticipation.

Lastly, much like the lack of a trailer for Spider-Man: No Way Home , Spidey's Tom Holland's MIA status may seem surprising.

However, it's important to note that Disney shares the character with Sony Pictures making appearances by Holland and web-slinger a truly tangled web. Plus, like Brie Larson, scheduling conflicts and contract terms may have prevented the possibility altogether.

What If...? begins streaming on Disney+ on August 11, 2021.
