Ever since it was announced back in October that Captain America 3 would be subbed Civil War, people have been talking about what it could be. However most of the initial comments were not that great, basically saying that you can not make a movie based off the Civil War story arc without Spider-Man. He was an integral part of the story.
Now that it has been announced that [Marvel](channel:932254) Studios has the rights to use Spidey int their films, everyone is happy. Right? Most are really excited now that we can see a "proper" interpretation on the big screen of one of the best story lines to come out the comics in recent years. However, I don't think fans really understand what is taking place to set up Civil War. Lets take a look at what we know with a little bit of speculation thrown in for good measure.
Beware some spoilers ahead.
First of all, Civil War is about the Superhuman Registration Act. All super powered beings that where a mask needs to register their names and powers with the government so that they can be held accountable for their acts. While I can see a part of this playing out in the cinema (especially after Age of Ultron), we haven't seen many hero's that keep their identity a secret. Tony Stark announced on television he was Iron Man, anyone who knows about WWII also knows Capt. Steve Rogers is Captain America (there is even a museum exhibit about him in Winter Soldier), Thor does not seem to even attempt to hide who he is, neither does the Hulk (unless you count trying to keep is anger in check as Bruce Bannner), and [Black Widow](movie:1070824) dumped all the files of S.H.I.E.L.D. onto the internet revealing identities of any known affiliates (herself, Hawkeye, etc.). So we know who these people are already, which brings me to my next point.
Tony Stark convinces Spider-Man to unmask in a live press conference. With no mention of Spidey or Peter Parker in previous films, it would be hard to say that this would have the impact that it did in the comics. The same would go for Spider-Man switching sides. It would be too much set-up to be done for a supporting role. (Yes a supporting role.)
It is Captain America 3, not Spider-Man. As you look further into it they already have several supporting characters cast for the movie (including Falcon, Black Widow, and Black Panther). There are even rumors about the villians being Baron Zemo and Brock Rumlow a.k.a. Crossbones, whom actually kills Cap in the end of the Civil War comics.
The point that I am trying to make is this. People are getting too excited over Captain America 3: Civil War for the wrong reasons. Yes, Spidey may make an appearance, but I think that will be the extent of it. Just an appearance. Anything more would just make what could be a great film that we have come to expect from Marvel Studios into something more like what we would got from Sony this past year.
