Glengarry Glen Ross
Writing about web page http://www.imdb.com/title/tt0104348/
My favourite film is Glengarry Glen Ross which is about the miseries of a bunch of salesmen pitched to compete against one another for their jobs. It was originally a play by David Mamet and was adapted for the big screen in 1992. The cast list alone tells you you're in for a treat and includes Jack Lemon, Al Pacino, Kevin Spacey, Alec Baldwin and Ed Harris. The thing that makes it is the sharp dialogue, which contains so much profanity the actors jokingly referred to it as 'Death of A Fucking Salesmen' during filming. It has quite a cult following and fans claim to be able to hold entire conversations with one another on any topic using only lines from the film.
