Save the Tiger (1973) - Jack Lemmon's Oscar Winning Role

The film takes place in about a day and a half in Harry Stoner's life. Harry is down on his luck, and trapped in his own indulgences. He daydreams about his youth, trying to escape from the fact that business is rotten and his company owes bundles of money. His day is filled with unusual episodes as he picks up a hitchhiker/prostitute, arranges for his company's warehouse to burn down so he can collect the insurance-money, he hires strippers for his buddies and gets engaged in an animal rights campaign, a fashion show and experiences a rather uncomfortable flashback to the war.
