"No more mutants."
That is what the Scarlet Witch said in the House of M comic book storyline but this is not about the comic book universe, this was just a good way to start this theory post. This is about the movie universe, specifically, the Marvel Studios cinematic universe.
So let's talk
The Avengers 2 or
The Avengers Sequel, whichever you want to call it. What do we know about it? Not much.
We know Joss Whedon is still writing the script, the movie should start principle photography in the first half of next year and we know that the core Avengers team will be back.
But what does that mean? Core Avengers team? It means Iron Man, Thor, Captain America and the Hulk will all be back. That's your core team. Not the Black Widow or Nick Fury or Iron Patriot or the Falcon. It's those four superheroes whose Phase 1 movies led to the first ensemble movie and they are the only definite heroes who will back for the big sequel. At least as of right now and until official announcements are made as to which heroes will be in it.
One of the big reasons this all needed explaining is due to the fact many fans think all of the secondary characters will make an appearance in The Avengers 2. Well this may not the case.
There are already rumors traveling around the Internet saying that Fury or Hawkeye or Widow may not be back and some of those will be right. Others will be wrong. One thing is clear and it's that Whedon is bringing new heroes to the team.
He has already been on record talking about a brother and sister duo which is obviously the Scarlet Witch and Quicksilver. But the one thing to remember about these siblings is that they're mutants and Marvel Studios does not have the movie rights to mutants (Fox does) or even to say the word mutant in the MCU.
Which brings us to our point. After discussing some Avenger and screenwriting theory with a close friend who has done actual Hollywood scripts in the past it was agreed that while Whedon is writting his script for The Avengers 2 he has to be considering new origin stories for the Scarlet Witch and Quicksilver. Yup, that is where it gets all "Trevor Slattery". (Definition: Trevor Slattery. To drastically change a character on the big screen compared to his/her comic book version where fans freak the f**k out. This is a thing now, right?)
All jokes aside, how Whedon will go about explaining the duos powers is beyond comprehension right now since he cannot call them mutants nor can he reference their father Magneto. That is, unless Marvel can strike some deal with Fox but let's not get too far into any of that speculation or theory right now.
We have
The Avengers Sequel to worry about, not a possible giant Marvel Studios-Fox crossover movie that will most likely never happen.
What are your thoughts on what might be done with the brother/sister duo since Marvel cannot call them mutants?
