There's a minor war brewing between 20th Century Fox's X-Men: Days of Future Past and Marvel Studios' The Avengers 2. Both franchises hold the right to use characters Quicksilver and Scarlet Witch, mutant siblings of Magneto and substantial members of both superhero teams. The catch is, Fox can never mention the Avengers, and Marvel Studios can never explain that they are Mutants, or mention the name of their father.

Shortly after The Avengers 2 director Joss Whedon confirmed both of the characters would have significant roles to play in his sequel, director Bryan Singer announced that he had cast American Horror Story mainstay Evan Peters as Quicksilver in his film. This came as a shock to many, as the character has never been utilized by the X-Men franchise over the course of six films, and until last week, it didn't look like he'd be making an appearance in X-Men: Days of Future Past either.

To a lot of fans, the casting announcement came from out of left field, and read spiteful on the studios' behalf. Right now, its believed that the character has a very minor role in X-Men: Days of Future Past, in one action sequence that supposedly needs his, and only his, Mutant power of speed. Joss Whedon appeared on Late Night with Jimmy Fallon Friday night, with many hoping he would address this controversy.

He spoke nothing of Fox and Bryan Singer's recent casting announcement. Instead, he talked about the characters, explaining why he wanted to use them, and that casting is currently in the midst of happening right now. While some speculate that this move is trying to tie the two franchises together, that's highly unlikely. Evan Peters is 98% confirmed not to be playing Quicksilver in The Avengers 2, but that could change. Stranger things have happened.

Check out Joss on Late Night with Jimmy Fallon, then read on for his quotes.

"There are new characters. I've already said that we're going to have a brother-sister team, the Scarlet Witch and Quicksilver, who were great mainstays of The Avengers when I was reading the comics as a kid. Besides the fact that I grew up reading them, their powers are very visually interesting. One of the problems I had on the first one was, everybody basically had punchy powers. 'I can hit,' 'I can also hit.' 'I can hit harder' That can get boring in a two hour movie. Hoepfully it didn't get too boring. But coming into the second one, he's got super speed. She can weave little spells and a little telekinesis, get inside your head. There's good stuff that they can do that will help keep it fresh."

While Evan Peters is confirmed as Quicksilver in X-Men: Days of Future Past, the character has yet to be cast in The Avengers 2. Joss has made it known that he is tailoring his Scarlet Witch after young Hanna star Saoirse Ronan, and its likely that she will be confirmed within this next week. Might we suggest Justin Bieber as Quicksilver in The Avengers 2? Who do you want to see?
