Quicksilver Problem

     So who's heard of the new X-men movie coming out?  Fox is in production right now of their new film, "X-men: Days of Future Past."  This would be a no news kind of movie, as it's just another addition to a franchise, however, something interesting has occurred in the last several days.  Fox has released that they've added a new character, and actor to the roster or their new film.  The character, "Quicksilver," has been added to the cast of characters.  Now, Quicksilver is the super fast Mutant of the X-men universe.  Fox has also announced that actor Evan Peters will be playing the character.
     This brings up an interesting problem, as Marvel Studios had written the character into their upcoming movie, "The Avengers 2."  Joss Whedon, Director of the Avengers, had stated he had perfect use for the character in the Avengers sequel.
     The problem with this is that Fox owns the movie rights to all "X-men" characters.  However, Quicksilver is still a Marvel character (as Marvel owns the X-men).  The issue, now, is who is allowed to use the character in their movie.  Fox has already begun production on their film, and Marvel is still in early Pre-production.  The obvious choice is that Fox gets to keep doing what they're doing, but now Marvel is going to have to make drastic changes to their story.  This is the first time that a character has been wanted for two separate franchises.
     This comes down to different studios having control over different entities, owned by the same company.  Fox knows they have a cash cow with the X-men films, just as Sony knows they have one with Spiderman.  Marvel has been trying to gain control of their characters back, and is slowly achieving their goal.  However, with Fox and Sony holding their characters hostage, it might be a while until Marvel owns the movie rights back to all their characters.
