An erotic drama with some weird things going on....I have not seen it but know about it.
Greenaway ,the director, makes strange intense films ,but many have an erotic center to them then things can go south.and get dangerous or weird. I have only seen one of his- 'The Cook, the Thief, His Wife, and her Lover ....Helen Mirren and Michael Gambon are in that one....a good but intense film that might not appeal to all.
BTW....I enjoyed Doctor Sleep (a sequel of sorts to The Shining) with Ewan Mc Gregor , who is in Pillow Book.
