Bugsy Malone is a musical movie, very loosely based on events in Chicago, Illinois in the Prohibition era, specifically, the exploits of gangsters like Al Capone. The tongue-in-cheek movie stars children as the gangsters and their molls. The plot concerns the manufacture of a brand of killer custard, which is used first in pies then later in splurge guns to kill people. The musical centres on Fat Sam's Grand Slamspeakeasy.
