The Cook, The Thief, His Wife & Her Lover

Released in 1989, the cook, the thief is a satirical drama with lots of violence and much more strangeness. When first released, it was an X rating.
Despite its oddness, the costumes and costume changes make it worthwhile.
Throughout the film, the costumes change depending on the room.
Red in the dining room, green in the kitchen, white in the toilets and black elsewhere creating an artificial atmosphere.
I personally think the film is about sex (due to the affair),food/ gluttony (it is mainly based around the eating of food)and murder/ revenge (through the violence and various acts.)
