Diamond Skulls (also known as Dark Obsession) is a British 1989 thriller directed by Nick Broomfield who also co-wrote with Tim Rose-Price.

[2] It is produced by Tim Bevan and Jane Fraser and stars Amanda Donohoe, Gabriel Byrne and Struan Rodger and has a music score by Hans Zimmer.

The police believe the story and close the case, and the amoral Hugo gets away with everything as he continues his sordid and unwholesome life undisturbed.

In this movie Amanda Donohoe was faced with the added pressure of simulating sexual intercourse with another actor in front of director Nick Broomfield, with whom she was developing a romantic relationship.

[6] In the New York Times review Diamond Skulls; Aristocracy When It Thinks No One is Looking, Janet Maslin considered that "rarely does a documentary film maker make the transition to fiction as adroitly as Nicholas Broomfield has in Dark Obsession, a psychological thriller displaying a documentarian's fascination for small, telling details."
