Possession - 1981 - Andrzej Zulawski
Driven by a scenery chewing performance by Sam Neil as a family man whose wife, played impeccably by Isabelle Adjani, may or may not be having an affair with an other worldy demon. The story plays out like a traditional infidelity drama until Adjani's character begins a sexually charged epileptic fit amid daytime traffic. As her finger nails begin to bleed and the milk like vomit propels from her mouth you know the "other man" might be working with a little something extra. Great physcological drama with some old fashioned monster movie scares as well. The creature in the film was designed by the same team that created E.T. Go figure.
