I've been trying to find this 1988 Italian Noir movie for years. I've finally tracked it down and although it leaves a bit to be desired on the plotline front, it looks amazing. It was directed by Ivana Massetti, an Italian director of pop videos & commercials...and it shows. It features the statuesque Brigette Nielsen who plays a video director living in a dark Art Deco apartment with a bejeweled tortoise and a black mannequin 'bodyguard'.
This scene depicts her awesome apartment:
