The 20th Century Fox superhero sequel X-Men: Days of Future Past is turning into an X-Men reunion, with Bryan Singer set to direct and Patrick Stewart and Ian McKellen already confirmed to return along with Wolverine himself, Hugh Jackman.
It isn't clear if 20th Century Fox has issued formal offers to the actors, or any of the other X-Men stars. It isn't known if others such as Anna Paquin (Rogue) are being sought to reprise their roles, but there is said to be a lot of "willingness to participate" because of director Bryan Singer returning to the helm. The X-Men stars will reportedly appear in scenes that show a dystopic, alternate future, with Kitty Pryde playing a major role in the action.
Sumela Kay played the character in 2000's X-Men, with Katie Stuart assuming the role in X2: X-Men United. Ellen Page, the most well-known of the three actors, took on the part in X-Men: The Last Stand, with the character playing a key part in that film. It is not know at this point if any of these three actors will return. In the animated X-Men series from the 90s, their adaptation of X-Men: Days of Future Past traded Kitty Pryde for the character Bishop. We have no word on how Bryan Singer plans to change or utilize Kitty's role in the storyline.
