The Long Good Friday (1980)

Synopsis
John MacKenzie's masterfully directed British crime drama features a star-making performance by Bob Hoskins as Harold Shand, a successful London gangster whose world falls apart over the course of one weekend. Shand controls the London docks and is planning a big real estate deal, financed by money from the American mob and given the okay by the London organization. His world is sweet -- he lives in a fancy penthouse, he owns a yacht, and has a sensitive and intelligent mistress. But suddenly a bomb explodes inside his Rolls Royce, another bomb destroys a pub he owns, and a third is found inside his casino. Shand can't understand who would suddenly want him dead, particularly over the Easter weekend, when representatives from the American mafia are coming into town to discuss investing in Shands's real estate project. ~ Paul Brenner, All Movie Guide
