From the drug-fueled excesses to the punch-ups and knife fights, these films depict society's underbelly in action. Whether it's holding up the local liquor store or wheeling and dealing among the far-reaching tentacles of organized crime, the truth is never far from the fictional world on the big screen. The gangster genre kicked off with actors such as James Cagney and Edward G. Robinson. Their tough-guy looks set the trend to follow, and led to the devious, crazy, and charismatic crooks played by the likes of Al Pacino and Robert de Niro. But often these hard men are almost sympathetic characters: Marlon Brando's godfather turned bad to feed his family, after all - capisce? The one-line quips, the sharp suits, the sense of camaraderie, and the grisly killings have created some of the movies' most memorable moments. So get ready to take a walk on the wild side.
