A Hatful of Rain, based on the stage play by Michael V. Gazzo, is the story of a drug addict's debilitating effect on his family. Don Murray has managed to keep his addiction secret from his pregnant wife Eva Marie Saint and his boorish father Lloyd Nolan, but Murray's brother Anthony Franciosa knows the truth.
Murray hits up Franciosa for money to support his habit, but even this is not enough as the addiction deepens and Murray finds himself beholden to a vicious pusher (Henry Silva). Murray is unable to cope with his private hell until he confesses to his wife and father that he's a junkie and needs help.
Considered the last word in realism in 1957, A Hatful of Rain seems slightly antiquated in the light of the drug-abuse excesses of the 1990s.
