The cast of X-Men: Days of Future Past represents both the stars of the original trilogy (X-Men, X2: X-Men United and X-Men: The Last Stand) and the younger versions of these characters that debuted in 2011's X-Men: First Class. 20th Century Fox has been highlighting each mutant in the series with new photos. Today, Halle Berry's Storm takes center stage, marking her first return to the franchise since 2006's X-Men: The Last Stand. Since this sequel takes place both in the 1970s and in present day, do you think we may get our first glimpse at a younger Storm in X-Men: Days of Future Past? We'll find out for certain when director Bryan Singer's superhero sequel hits theaters May 23.
