Prior to the release of Avengers: Infinity War, one of the biggest rumors that people kept spreading online was that a post-credits scene would debut Captain Marvel. I’m not talking about the beeper scene like we got, people were seriously expecting the movie to introduce the character and have Brie Larson show up at the end of the movie.
In an interview with the Infinity War screenwriters that Collider did, they say that was never their intention:
“We want [Captain] Marvel to be introduced in her own movie.”
So there you have it. Carol Danvers won’t make her MCU debut until next March. It won’t be long until we get our first look at her, as we’re likely to get a teaser trailer for Captain Marvel sometime this summer.
