Doctor Strange and Steve Rogers Will Interact for the First Time in Avengers: Doomsday

In Doomsday, during the third act of the movie, Boris will have a conversation with Steve Rogers at Doom’s Castle. Boris will then remove his mask, revealing himself to be Doctor Strange.

Strange will explain everything that happened following the events of Doctor Strange in the Multiverse of Madness, including why he chose to help Doom and why the incursions can’t be stopped. This will be the first time Doctor Strange and Steve Rogers have interacted in the MCU.

In a recent interview, Marvel Studios boss Kevin Feige said Avengers: Doomsday is a special film that will allow Marvel Studios to do things it couldn’t do with Avengers: Endgame. Feige teases a literal cosmic collision involving some of the fans’ favorite characters from each universe.

Feige said, “This time we can do some things we couldn’t do with Avengers 4, which is to bring in some of Marvel’s most iconic characters: the biggest being the X-Men, then the Fantastic Four, and of course, Victor von Doom/Doctor Doom.

These characters weren’t even in our ‘toybox’ during the Infinity Saga. Only when we bring these characters back can we tell the grand story of Avengers 5 and Avengers 6, including a literal cosmic collision, with some of your favorite characters in each universe.”

Directed by Anthony and Joe Russo and written by Stephen McFeely, Avengers: Doomsday stars Robert Downey Jr., Chris Evans, Chris Hemsworth, Pedro Pascal, Paul Rudd, Anthony Mackie, Florence Pugh, Vanessa Kirby, Ebon Moss-Bachrach, Wyatt Russell, Channing Tatum, Simu Liu, Ian McKellen, Tom Hiddleston, James Marsden, Patrick Stewart, Joseph Quinn, Sebastian Stan, David Harbour, Letitia Wright, Lewis Pullman, Kelsey Grammer, Danny Ramirez, Winston Duke, Alan Cumming, Wesley Holloway, Hannah John-Kamen, Rebecca Romijn, Alex Livinalli, and Mabel Cadena, with Tenoch Huerta Mejía.

In Avengers: Doomsday, beloved heroes from three distinct universes are set on a deadly collision course, facing an existential threat unlike anything they have ever encountered.

The film is produced by Kevin Feige, Louis D’Esposito, and Jonathan Schwartz, with Callum McDougall serving as executive producer.
