The first trailer for Marvel's What If....? has been released. The animated show hits Disney+ on August 11.

　　The series dives into various Marvel multiverses and the many possibilities for its characters beyond what has happened in the Marvel Cinematic Universe. The trailer opens with a familiar scene of Tony Stark from the first Iron Man movie, but the sudden appearance of Black Panther's Eric Killmonger quickly reveals that this isn't the MCU as we know it.

　　From there we see familiar characters such as Dr. Strange, Spider-Man, and Thor mixing with Howard the Duck and Captain Britain--who, in this case, is the alias of Captain Peggy Carter. T'Challa is now the leader of the Guardians of the Galaxy, and there's a voiceover from the all-seeing Beyonder, played by Westworld's Jeffrey Wright, who teases a "journey to face the unknown." Check it out below:

　　What If...? features voiceovers from many of the actors from the MCU, including Chris Hemsworth as Thor, Hayley Atwell as Peggy Carter, Josh Brolin as Thanos, Tom Hiddleston as Loki, Dominic Cooper as Howard Stark, Karen Gillan as Nebula, Michael Douglas as Hank Pym, Michael B. Jordan as Killmonger, Jeff Goldblum as Grandmaster, Michael Rooker as Yondu Udonta, Paul Rudd as Scott Lang, Mark Ruffalo as Bruce Banner, and the late Chadwick Boseman as T'Challa.

　　Season 1 of What If...? will feature 10 episodes, and there's already a second season in the works. In an interview with Discussing Film in 2019, showrunner Ashley Bradley explained that the show will mix up the events of the movies in unexpected ways. "We will be exploring every movie in a new way, but not every episode is about one movie if that makes sense," he said.

　　"On the reel [shown at D23 Expo], there is this image of a Star-Lord T'Challa because we wanted to see what if the worlds of Black Panther and the Guardians of the Galaxy collided? That was taking two universes, two to three movies, kind of twisting them in new ways."
