Among the more plausible-sounding rumors, we’ve heard that Samuel L. Jackson might come back in his role, and while many would be happy to see Nick Fury back on the screen, we don’t actually know if this is planned yet.
Other than that, we frequently see rumors about the main villain of the film as well as other interesting points of its plot, but we would wait for an official announcement to confirm these plot details instead of focusing on speculation so much. It’s not that surprising that we’re hearing so many different claims about the film in any case.
After all, when it comes to a major production like this, it’s pretty much guaranteed that some fans will let their imaginations run wild and discuss various possible developments that they would like to see happen, whether they are founded in reality or not.
At the same time, those who don’t want to spoil the experience for themselves should avoid following those discussions too much as they can create the wrong impression for the final product, and we’ve seen this happen before with other films. Fans of the Marvel Cinematic Universe have probably learned a thing or two about following rumors so actively at this point though, so we would expect them to approach this with a bit more caution. In the meantime, it’s still fun to see what fans are thinking about the next film.
