Captain Marvel fans are using anything they can find to come up with theories about Avengers 4.
Brie Larson , the actress who portrays Captain Marvel posted on Twitter this week encouraging people to vote.
In the tweet she also posted a photo of herself on the set of the Captain Marvel in a pay phone booth.
People immediately zoomed in on a few clues to make predictions about the future of the Marvel world.
Chris Smith of BGR had this to say about the timeline of the film and what it could mean.
"The confirmation that Captain Marvel takes place in the early 90s is essential nonetheless. We may not see Doctor Strange or Tony-from-the-future in Captain Marvel, but the film will undoubtedly tell us what happened to Fury in the past and why Captain Marvel left Earth."
"It'll also deliver the final puzzle pieces ahead of Avengers 4. Of course, it wouldn't be surprising to see Doctor Strange in the credits scenes of Captain Marvel."
And a Reddit user Reddit sfmarch07 put out this theory:
"Tony is going to have to sacrifice something, the same way Thanos had to sacrifice Gamora."
"But instead of sacrificing Pepper Potts, what if Tony instead has to go back in time to 1991 and infiltrate Hydra or seek out the Winter Soldier, and order the hit on his parents himself, sacrificing the thing he loves most, to enable him to get the Soul stone to fight against Thanos, knowing all the while what it will cause in the future and all the anguish it will personally cause him along with the events of Civil War, breaking up the Avengers, and everything that happens after that."
We aren't sure what is going to happen but the series certainly keeps people guessing.
There are a lot of theories floating around.
We certainly know how you feel.
Everyone will have to wait until March 2019 to see if their theories for Captain Marvel are true. The movie is set to be released in the USA on March 8, 2019.
