As Captain America: Civil War is gearing up to finally start production next week, it's likely more and more pieces of information will be coming to light. I'm guessing people are already trying to find the best spots in Atlanta to snap set photos from and sneak peeks of the cast of what is essentially turning out to be Avengers 3 (or Avengers 2.5 as it is rumored to have been called around the Marvel offices).
Civil War Web Casting
It makes sense that as filming is about to start on Captain America 3, more news would emerge on the casting of Spider-Man. While it hasn't even been confirmed that the character would be making his debut in Captain America 3, there really isn't a more likely Marvel movie that would fit the contract stipulation that Sony and Disney agreed on.
But both the rumor that 16-year old Mateus Ward, an actor best known for his roles on the television shows Weeds and Hostages, was auditioned for Spider-Man and the fact that Marvel comics chief Joe Quesada responded to a question by saying, "The trick to making any incarnation of Spider-Man great, whether comics, animation or film is Peter Parker. Get Peter’s character right and the rest falls into place," nearly confirms that Sony is actively looking for a Peter Parker and making good on their promise to bring the character back to high school.
Civil War Re-In-Actors
This Spider-Man audition news emerged at the same time Captain America: Civil War received a semi-official synopsis and a rumor about the movie's superhero line-up came out and got swiftly debunked. Bleeding Cool thought they may have received a scoop when, on top of the confirmed Captain America 3 personnel of Captain America, Iron Man, Black Widow, Hawkeye and Black Panther, it went on to add Hulk, Thor, War Machine, Scarlet Witch, Wasp, and Spider-Man.
There are more than a couple reasons that this list is suspect, and was quickly debunked - but the most glaring is the inclusion of Thor in the lineup. Those who have been following the rumors and plot leaks leading up to the release of Avengers: Age of Ultron have heard that when the movie ends Thor has headed back to Asgard to deal with the events of Thor: Ragnarok.
The Disappearance of Hulk & Thor
We've heard Joss Whedon talk plenty about how Avengers 2 will be dealing with the disintegration of the Avengers team as we know it. Naturally, as the movie is feeding into Captain America: Civil War, this is understood to be the case - but it is also expected to mean that some of the members of the Avengers are going AWOL and not sticking around to witness or choose sides in the Captain America vs Iron Man showdown.
We've gotten plenty of glimpses as to how Scarlet Witch will be fighting on the side of Ultron during the first half of Avengers 2 and the hex that she puts on Thor and the Hulk are likely to put both of these characters out of the picture in Captain America 3. Thor will likely discover that with Loki running things in Asgard, the apocalypse is soon to be underway in [Thor: Ragnarok](movie:956858). And the whammy that Scarlet Witch lays on Bruce Banner and the Hulk will lead to him either being deemed to dangerous and locked up by Nick Fury or we'll see Bruce Banner doing one of his famous remote location hideaways.
Re-Assembling the Avengers
What is interesting about some of these new reports that came out along with the new Captain America: Civil War information is that it seems likely we won't be seeing many of these Avengers back together again until Avengers: Infinity War Part 2. A good part of this Phase 3 will be focusing on introducing characters like Ms. Marvel, Doctor Strange, Black Panther and the new Spider-Man and Infinity War Part 1 may be in place to focus on combining these characters rather than working on getting the old gang back together.
If [Captain America: Civil War](movie:994409) is indeed intended to lead directly into the Avengers: Infinity War movies, and the official word of keeping the Russo Brothers as the directors for all three of these movies makes this seem apparent, it looks like Marvel is building an amazing character arc for the original Avengers team that could see them broken apart at the beginning and finally healed, in one way or another, by the end of Phase 3.
