Two additions to this list (which is pretty good):

Alicia Vikander in Ex Machina. Her performance is controlled, warm when it needs to be, yet somehow alien, foreign. Her ballet training is as much the star as her acting (which is excellent), but that’s not a bad thing. Ava might be an android, but Vikander makes her breathe.

And Elle Fanning in Super 8. She is the only reason to watch that film — her stark, empathetic and wounded performance just blazes off the screen. In this film she is simply amazing and the movie also has the best example of meta-acting that I’ve ever seen (also from her, of course). She’s the best under-twenty actress out there by a long shot and her character feels like the only real one in Super 8. The movie should’ve by all rights been told from her POV.
