This film tries to be much more clever than it actually is. An aristocrat, empty and brutal, runs down a woman while the worse for drink at the wheel of his car. The woman resembles his wife more than a little. Murder, or mistake? Gabriel Byrne, in the stage of his career when he was still playing low-lifes, bad guys, and simmering sadists, is OK as the lead character, Hugo. Sexy Amanda Donohoe has another interesting role to set against her big break in 'Castaway' a couple of years earlier, but there is little chemistry between her and Byrne - it can't have been an easy film to do, though.
As a depiction of ruling Britain, 'Diamond Skulls' falls into the trap of showing drunken, orgy-obsessed cretins who serve very little purpose. It tries to be both intellectual and psychological, but Nick Broomfield's direction is muddled and the film is a mess.
