Bryan Singer has cast a new mutant cast-member to 'X-Men: Days of Future Past'.
Evan Peters, star of TV horror series 'American Horror Story', is to join the all-star cast as Quicksilver.
As seems customary at this stage, director Singer confirmed the news through his heavily-utilised Twitter account.
“Before he was an #Avenger, he was just a REALLY fast kid. Thrilled to say #EvanPeters is joining #XMen #DaysOfFuturePast as #Quicksilver,” he wrote.
Though it might seem to be an innocuous casting announcement, it may have further ramifications in the world of Marvel Comics on the big screen.
Joss Whedon revealed last month that he is also planning to introduce both the Quicksilver character and Scarlet Witch, Quicksilver's sister, to his sequel to 'Avengers Assemble'.
The issue here is that while 'X-Men' is produced by Fox, 'The Avengers' are part of the Marvel Comics deal with Disney.
It's not known yet whether Peters will star as Quicksilver in both films, but contractual wranglings between rival studios could make that a tricky possibility.
To give context, Quicksilver and Scarlet Witch are the children of 'X-Men's Magneto.
Whatever, Peters is joining a sterling cast for Singer's sequel.
Among the players are Sir Ian McKellen, Sir Patrick Stewart, Michael Fassbener, James McAvoy, Hugh Jackman, Halle Berry, Ellen Page, Peter Dinklage, Anna Paquin, Shawn Ashmore, Omar Sy and Jennifer Lawrence.
'X-Men: Days of Future Past' is due out on July 18.
