In the wake of Marvel Studios and directors Joe and Anthony Russo launching their #ThanosDemandsYourSilence campaign Sebastian Stan dropped a pretty big Avengers: Infinity War spoiler while he was doing an interview with Letitia Wright for Glamour UK. The #ThanosDemandsYourSilence was a request for fans to not spoil the movie. Sebastian Stan must have missed the memo.

Stan talks about a pretty epic scene during either Avengers: Infinity War or Avengers 4 where he reveals some characters show up that you might not have been expecting.

Stan describes the scene:

“There was one scene, I think we had where everybody was there. I can’t really talk about that scene, but I knew it took them three months in planning this scene to have everyone there. You looked around and just saw everyone from Samuel L. Jackson to Michael Douglas, Michelle Pfeiffer, everybody was there. I kind of just stood in the corner and looked, and wanted to see how everybody would interact. But it’s surreal.”

While Stan didn’t describe the scene or what exactly was going on in it. He did reveal that Samuel L. Jackson, Michael Douglas, and Michelle Pfeiffer were all there. Samuel L. Jackson had previously talked about how he wasn’t going to be in Avengers: Infinity War. However, we suspected that to not be the case when leaked set photos showed him in his Nick Fury costume from the Marvel Cinematic Universe.

But maybe the biggest reveal is that we have the old school Ant-Man and Wasp on set. With them on set that leaves a number of possibilities on the table. The most obvious is time-travel. We already know it’s going to take place. Doctor Strange mentioned it to Iron Man in a TV commercial. However, he only mentioned traveling to the future. It’s quite possible it might be used to travel into the past as well.

But maybe the biggest thing that comes to my mind is a huge power move by Thanos. He acquires all of the Infinity Stones and fully powers the Infinity Gauntlet. He then brings all of the Marvel heroes to him and choose who would live or die. It’s pretty brutal, but I can definitely see Thanos doing something like that. It could also be a future scenario where all of Marvel’s heroes have gathered in an attempt to defeat Thanos.

Either way I can’t wait to see this absolutely epic scene when Avengers: Infinity War hits theaters on April 27, 2018.
