Bob Hoskins plays George, a tough but basically goodhearted British mob flunky, recently released from prison, where he'd served a term to cover up for his gangster boss (Michael Caine). Still willing to be everyone's doormat, George agrees to act as chauffeur for Simone (Cathy Tyson), a haughty, high-priced call girl. They don't like each other at first, but George begins to fall for her and take a protective interest. She implores him to help her find her only truly friend, a prostitute named Cathy (Kate Hardie). Touched by this devotion, George locates the girl, only to be chagrined to learn that Simone and Cathy are lovers. Hoskins is used and abused by so many people in Mona Lisa that when the worm finally does turn, you feel like cheering--even though it doesn't make him any happier. Director Neil Jordan cowrote this study of underworld mores with David Leland.
