''Less Than Zero'' is a 1987 film based on the [[Literature/LessThanZero book of the same name]] by Creator/BretEastonEllis, starring [[Creator/BratPack Andrew McCarthy]] as Clay, [[Creator/BratPack Jami Gertz]] as Blair, Creator/RobertDowneyJr as Julian and Creator/JamesSpader as Rip, Julian's drug dealer.

The film was noted for taking [[InNameOnly extensive liberties]] with the plot of the novel. In a curiously PostModern touch, the film adaptation actually exists within the universe of the ''Literature/LessThanZero'' book: the opening of the book's sequel, ''Imperial Bedrooms'', discusses the adaptation at length.
