Yesterday, Marvel Studios kept fans on their toes with a brand new trailer for Doctor Strange In The Multiverse of Madness. The new footage featured big reveals such as Lashana Lynch playing Maria Rambeau variant of Captain Marvel, the voice of Patrick Stweart as a Professor X variant (bringing X-Men into the MCU), and a possible tease of The Savage Land (The location of Ka-Zar and dinosaurs hidden in Antarctica).
Well, the film’s new poster also has confirmed a long-standing rumor for the newest MCU installment.
Hayley Atwell played a variant of Captain America in the animated series What If…? as the series dealt with the Multiverse plenty of fans assumed she would appear in the Doctor Strange sequel. That has been confirmed as we’ve spotted Captain Carter’s shield with the British Union Jack on it is clearly on the bottom right hand corner of the new poster.

Does that mean Atwell is 100% in the role? Time will tell.
More online rumblings have suggested every Marvel character in existence could appear in the film, but we have to assume the group is going to be much more narrow than that given we need an actual film, not just fan-service cameos.
Doctor Strange In The Multiverse of Madness debuts in theaters on May 6th.
