Some Seriously Dark "Humour": The Cook, the Thief, His Wife & Her Lover
In my opinion one of the greatest movies ever made, but seriously dark, brutal and nothing for the the easily-offended. Peter Greenaway's classic from 1989 ( I had the honour to watch this movie at a small festival with him being present, and I had just about reached the age to even be allowed entrance).
Contains sex, brutality, cannibalism and classic paintings... I do not recommend to watch it over dinner. But it has some insanely ironic elements to it. Last but not least a stellar cast: Helen Mirren, Michael Gambon and others.
