The Survivors (1983)

Synopsis
Director Michael Ritchie spoofs survivalists in this rambling black comedy. Donald Quinelle (Robin Williams) is a successful young executive who is called to his boss' office one morning and is fired by a parrot sitting in the CEO's chair -- a method the company uses to axe high-powered execs. Donald meets Sonny Paluso (Walter Matthau), a former gas station owner who is out of work because his business was blown up. At a diner, the two newfound friends witness a robbery and catch sight of the perpetrator, Jerry Reed (Jack Locke). Reed is a mob hit man who swears to kill the two men who saw him commit the crime. Donald, formerly afraid of weapons, becomes obsessed with guns as a way to protect himself from the mob. He enrolls in a survivalist training school in the mountains of Vermont. ~ Michael Betzold, All Movie Guide
