Swimming With Sharks
So your boss is cruel and abusive. So what happens when his whipping boy has had enough. Trouble of the criminal kind. Kevin Spacey is psychotic in this movie. You can't help but cheer on the poor sap who has had enough despite the viciousness of his revenge. (Kevin Spacey, Frank Whaley and Benecio del Toro)
Probably hits close to home for many of the exec assistants in LA, but is a hilarious, if dark, treat. Kevin Spacey in one of my favorite roles.
