Andrzej Żuławski (1940 – 2016) was a Polish film director. He is noted for the body horror film Possession (above), a powerful divorce allegory.
In Possession, Mark (played by Sam Neill) returns home to Berlin to find his wife Anna (Isabelle Adjani) is leaving him for an unclear reason.
He initially suspects an affair and snoops on his wife, but he gradually discovers clues that something far stranger is afoot. Instead, his wife leaves him and her lover, Heinrich (Heinz Bennent) for a bizarre experience with a strange tentacle creature.
