Less Than Zero (1987)

Quite enjoyed this adaptation of Brett Easton Ellis' 1985 debut novel, which deals with drug addiction and nihilism in the lives of rich white kids in LA during the 80s. Stars Robert Downey Jr (who would subsequently go on to explore the above-mentioned issues in his off-screen life), James Spader (one of my favourite supporting actors), Jamie Gertz (the girlfriend from Lost Boys who slipped into obscurity after her 15 minutes in the 80s), and Andrew Mcarthy (a fringe brat-packer whose 15 minutes went by almost as a quickly as Jamie's).
