Hailed as one of the all-time great comic book events, Civil War is one of those stories fans spent years hoping would one day reach the big screen.
Well, it's finally happening, and the movie is so far shaping up to be one of Marvel's biggest releases to date (the cast at least is certainly larger than in any other of the studio's movies). However, while it may be based on a well-known comic book, there's a lot about Captain America: Civil War which remains a mystery.
Spider-Man is going to show up and Captain America and Iron Man will indeed go to war, but beyond that, the follow-up to The Winter Soldier is a movie surrounded by speculation and rumours. How closely to the comic it will adhere isn't clear, nor is how it will fit within the wider MCU.
On paper, it seems to be another Captain America movie, with Iron Man a co-star and the rest of The Avengers just as the supporting cast, but as time's gone by it looks like a third Avengers in all but name.
So just what is Captain America: Civil War? Here, you will find a mixture of solid rumours and recently revealed details about the movie, along with answers to what have for a long time been unanswered questions...
10. It's Not About Secret Identities
In the Civil War comic book, the Superhuman Registration Act divided the world's heroes because so many of them were unwilling to reveal their identities to the government (mostly in fear of what would happen if that information were to go public and the ramifications such a thing would have in regards to the safety of their families).
In the film, however, it's the fact that signing up means they'd have to work for the government, only a sub-plot in the comics.
That's because no one in the Marvel Cinematic Universe really has a secret identity, something Kevin Feige acknowledged in an interview last year when he said that the "generalities of the act are the same" and "it’s not about the secret identity thing, as much as it is about, overall, who reports to who, and who can agree to oversight committee."
It's clear then that this movie will be a culmination of everything that's come before, with some heroes happy to be called into action when the government sees fit, and others unwilling to be used as pawns (no doubt in part because HYDRA's infiltration of S.H.I.E.L.D. proved it's hard to know who to trust).
