The trailer for Lucile Hadzihalilovic’s Evolution begins with a young boy discovering a dead body, and that’s not even in the top 10 of the creepiest things happening in it. There’s the fact the island seems to be populated solely by other young boys and very stern older women. There’s a lot of medical equipment around. And then... there’s the starfish. Look, just watch the trailer.

Evolution is a scifi film that’s short on action, but big on mystery and mood. After a festival run in 2015, it’s finally hitting theaters in New York on November 25, and will also be available on-demand.
