Rose Byrne Also Hasn’t Heard Anything About X-Men: Days of Future Past

“I don’t know, I haven’t heard what’s happening. I’m waiting to hear.”

If you recall back to X-Men: First Class, Byrne’s character did have her memory partially erased so it makes sense why her character wouldn’t be present for the sequel.

Cast members confirmed to return for the movie include Ian McKellen, Patrick Stewart, James McAvoy, Michael Fassbender, Jennifer Lawrence, Nicholas Hoult, and Hugh Jackman. X-Men and X2 director Bryan Singer also returns behind the camera.
Scheduled for release on July 18, 2014, X-Men: Days of Future Past features a script by Simon Kinberg and is said to be inspired Chris Claremont and John Byrne’s comic book storyline that ran in “Uncanny X-Men” #141 and 142 back in 1981. “Days of Future Past” introduced the idea of an alternate future for Marvel’s mutants that grew out of the Brotherhood of Evil Mutants killing an important senator, leading to a future where all mutants are hunted by Sentinels.
