Under the Skin (2013)

Okay that was weird (in a good way). Has nekkid Scarlett but you have to sit through child murder and erections to get there eek

It reminded me very much of the experimental sci-fi/horror of the late 70s/early 80s. The Man Who Fell to Earth, Artemis 8.1, Altered States, Videodrome and so on.
