Director Bryan Singer took to Twitter once again to announce new casting for his upcoming X-Men feature X-Men: Days of Future Past, the sequel to Matthew Vaughn's 2011 X-Men: First Class, and once again it isn't new names he's announcing, but returning characters.

If you weren't able to note the names through the Twitter speak, the returning cast members are Anna Paquin, Ellen Page and Shawn Ashmore who previously played Rogue, Kitty Pryde and Iceman in the original trilogy of X-Men films, which began with Singer's X-Men in 2000 and ended with Brett Ratner's X-Men: The Last Stand in 2006.
None of the actors listed above were seen in Vaughn's X-Men: First Class, but they will be joining several past X-Men stars that weren't seen in that film including Hugh Jackman, Ian McKellen and Patrick Stewart along with First Class stars James McAvoy, Jennifer Lawrence, Michael Fassbender and Nicholas Hoult.
The film is based on the Uncanny X-Men storyline "Days of Future Past" which deals with a dystopian alternative future in which mutants are incarcerated in internment camps. An older Kitty Pryde transfers her mind into the younger, present-day Kitty Pryde, who brings the X-Men to prevent a fatal moment in history which triggers anti-mutant hysteria.
The film is set for a July 18, 2014 release.
