This stunning VFX breakdown from Digital Domain, who worked on X-Men: Days of Future Past is a must watch. A lot of hard work goes into turning Jennifer Lawrence into Mystique. Sometimes it takes a whole other actor. The video shows the models and effects used for the scenes and much more.
It is amazing just how much work it takes to take the two actors and transform the scene. Oh and all of those amazing details at RFK stadium? That took a lot of work too and it looked great. Also check out Quicksilver’s VFX video. Great stuff. They are both very fascinating to watch.
