weird things in movie

if anyone watched closely there are some freaky things within
maybe I even missed some

on some scenes actor speech is different than what they talk
you can see this 1st time Ethan enters in car with Vivi
at specific moment sound of her is talking but her mouth are closed

another scene when Ethan teaches her daughter to ride a bike
again sound she talks, but her mouth closed

another again with Vivi when Ethan wakes with her at aquarium
he says "I don't want to spend rest of my life killing for you"
she says (sound says) "kill the Wolf", but her mouth show "kill the man"

then on elevator when Ethan goes to that last party
everyone has blue lips like their blood was sucked out
in fact the whole Hue of colors of their faces is changed
