I had heard about this before going to see the movie so I was looking out for it. Although it was quite impressive there were moments where their wrinkles seemed to "travel" or to pop in and out as if there was a layer mask that wasn't quite following their movements precisely. I'd have to see it again though just to be sure.
There is supposed to be a Magneto movie where both characters are much younger and they will supposedly be using this technology throughout the movie. Looks quite interesting.
I can just imagine both actors in overalls and rainbow beenies holding oversized lollypops and draging a little red wagon so that they can later be morphed down to 7 years old.
