"I'll probably use some of the motion-capture technology for certain things [in Days of Future Past]. And of course the 3D technology. I'll be shooting native stereo on X-Men," the filmmaker revealed to Cinema Blend.
Singer was also asked why he's been so secretive about revealing plot points for Days of Future Past, especially considering how open he was with First Class.
"There's things that we're going to do in this movie that haven't been done in X-Men films before," he responded. "Stuff involving [time travel], and stuff involving certain technology, and certain science fiction aspects that haven't been used before in an X-Men film. We'd like to keep some of that a surprise."
