Recasting X-Men: 14 Actors Who Need To Replace Singer's Mutants

Callisto sadly didn't really get an especially memorable treatment in The Last Stand despite the solid effort by Dania Ramirez, but considering her long-standing feud with Storm, now would be a perfect time to re-introduce the character to give the new, young Alexandra Shipp version of Storm someone to directly battle.

Yes, there's the slight awkwardness of Noomi Rapace being quite obviously over a decade older than Shipp, but you can blame the constantly time-shifting for issues such as this being commonplace and difficult to avoid.

On their own terms, though, Rapace and Shipp should play well off one another, and considering that Rapace has experience playing characters who favour black, she'll fit the look of Callisto like a glove.

Given that the Last Stand version of the character was embarrassingly inaccurate, this would be a ripe opportunity to get her right.
