As fans of the Marvel Cinematic Universe come up with their own theories about what will happen in Avengers: Endgame, the titular host of The Late Late Show with James Corden has offered his own insight into the superhero sequel.

It was an MCU reunion as Cobie Smulders (Agent Maria Hill) and Sebastian Stan (Bucky Barnes) came on the show and dodged questions about their potential returns to the franchise. Although both Hill and Barnes are currently dusted thanks to The Decimation, Corden explained what he thinks is really go on. “All the people that disintegrated to dust,” said Corden, “and all the people that say that, I think it’s a switch. I think all the people that disintegrated, they’re back and they carry on and all the people that stayed, they’re done.”

Smulders said, "Tag team," while Stan replied, "Interesting." The stars tried to move the conversation to Marvel's big 10-year photo from last year. However, Corden kept pushing, saying, "I'm right, right?" The duo still refused to acknowledge the idea.

There are various theories about how the dead heroes can return, with popular ideas ranging from alternate realities to time travel and even that they're simply trapped in the Soul Stone. The idea that the surviving Avengers will trade places in Endgame is an interesting one. Alongside the likes of War Machine and Rocket Racoon, all six of the original Avengers survived Thanos' snap. As it stands, Smulders is confirmed to return for the post-Endgame Spider-Man: Far From Home but there's no news on when/if Stan will be back.

It would be a heart-wrenching twist to see old favorites like Iron Man and Captain America bow out in Endgame. Chris Evans has repeatedly teased that he's done playing the First Avenger, and it ties in with Far From Home's tragic trailer theory that Tony Stark dies in Endgame. With just over three months until the Russo Brothers round off Phase 3 of the MCU, there isn't long to wait to find out whether Corden is right.

Avengers: Endgame will hit theaters April 26. Directed by the Russo Brothers, the film stars Robert Downey Jr., Josh Brolin, Mark Ruffalo, Tom Hiddleston, Chris Evans, Scarlett Johansson, Chris Hemsworth, Jeremy Renner, Chris Pratt, Elizabeth Olsen, Chadwick Boseman, Anthony Mackie, Sebastian Stan, Benedict Cumberbatch, Paul Bettany, Samuel L.
