Mona Lisa is a 1986 British film about a petty criminal who becomes entangled in the dangerous life of a high-class call girl. The movie was written by Neil Jordan and David Leland, and directed by Jordan. It was produced by George Harrison's Handmade Films. It stars Bob Hoskins, Cathy Tyson, Michael Caine, Robbie Coltrane and Sammi Davis.
George (Hoskins), recently released from prison, is given a cushy job as the driver for a high-class prostitute named Simone (Tyson) by his former boss, Dinny (Michael Caine). As George and Simone find out more about each other, they form a friendship despite possibly conflicting incentives. Central to this theme is Dinny's wish for George to find out as much as he can about one of Simone's 'regulars', a wealthy businessman seen with Dinny on one occasion. George then helps Simone in her quest to find an abused friend from her murky past, and this leads to a violent resolution in the seedy underworld.
