Evan Peters Cast As Quicksilver in 'X-Men': What Does This Mean for 'The Avengers'?

According to director Brian Singer's Twitter feed, "American Horror Story" star Evan Peters has just signed on to play Pietro Maximoff, aka the mutant superhero known as Quicksilver, in Singer's 2014 comic book epic "X-Men: Days of Future Past."

Just one problem: Joss Whedon has already revealed that Quicksilver is going to appear in 2015's "The Avengers 2."

Uh oh, you guys.

First, some background on why this character is appearing in two totally different franchises. In the comics, Quicksilver began his career as a member of Magneto's Brotherhood of Evil Mutants, helping Magneto fight the X-Men in the name of mutant equality. And this was before he even knew he was actually Magneto's son. However, he eventually had a change of heart, renounced his supervillain ways and joined the Avengers alongside his sister, Wanda Maximoff, aka The Scarlet Witch, another character Whedon has mentioned for "The Avengers 2."

So he's had one foot in both camps for a long time, frequently crossing back and forth between the X-Men and the Avengers over the past 50 years. Which is fine in the comics, but presents some major problems in Hollywood, because while "The Avengers 2" is being made by Marvel themselves, Fox has owned the rights to "X-Men" for over a decade.

What's the deal?

"We both have them," Marvel honcho Kevin Feige told Superhero Hype last year. "There's a specific arrangement with those two characters that would allow us to use them with 'Avengers,' but not discuss or reference their mutant or Magneto-related lineage. They can use them as mutants and as Magneto's relatives, but cannot have anything to do with 'The Avengers.'"

It's interesting to note that Singer's tweet originally read "before he was an #Avenger, he was just a really fast kid." But that part has been deleted from the casting announcement. Hmm.

Just what this actually means for "X-Men: Days of Future Past" and "The Avengers 2" is unclear. Will the movies feature completely different versions of the same character? Or are Sony and Marvel working together, meaning Peters would also appear in "Avengers 2" as Quicksilver (Saoirse Ronan is said to be in talks to play the Scarlet Witch in "Avengers 2" for whatever it's worth. Could they even be setting up a future crossover between the two movie universes? Or is that all just wishful thinking and this instead is simply a giant superhero clusterf**k bound to give confused moviegoers a massive headache?

One thing is for sure: Even Stan Lee couldn't write a melodrama like this. We can't wait to see what happens next.
