2. Black Panther = Spider-Man?
When it was beginning to look like Spider-Man wouldn't be included in Captain America: Civil War, there were reports that Black Panther would take his place in the story. That has since been denied, but if there was any truth to it, Panther's role may have been reduced somewhat. Perhaps not though, as a recent report claimed that his role is "significant". Don't expect to see the King of Wakanda choosing a side though as he will apparently have his own agenda in the movie which sets up the events of his solo outing in 2018. That could involve The Winter Soldier according to some, though there are a lot of conflicting reports about whether or not Bucky will be suited up as the new Captain America by that point.
