Motion Capture and the uncanny valley
Rotoscoping
An old version of animating the relies on an artist painting over an actors recorded motions. Films that use this technique include Snow White and the seven dwarfs, Gulliver's travels, Waking Life and A Scanner Darkly.
Motion Capture
Early uses of motion capture include Jim Henson's Creature Shop, Sexy Robot commercial, Don't touch me music video, The Lawnmower man.Some more recent examples of motion capture are The Last of us, Lord of the ring: the two towers, The polar express and Ex Machina. More modern motion capture involves Mo-cap suit and advanced computer graphics.
The Uncanny valley
An example of the uncanny valley used to an intentional effect is in Ex Machina, when the character of Kyoko (played by Sonoya Mizuno) peels off the skin just below her eye ball to reveal that she is an android like Ava (played by Alicia Vikander). This pushes the character of Kyoko from a beautiful Asian woman into a creepy replacement for a human being. This is designed to make the audience uncertain as up until that point we are lead to believe that Kyoko is human, and this scene shows us that she is certainly not.Sadly this video is the only example I can find of the scene.
