Cape Fear (1962) - J. Lee Thompson
Small-town lawyer Sam Bowden's life becomes torturous when Max Cady re-enters his life. Cady went to jail for 8 years after Bowden testified that Cady attacked a young woman. Now that Cady has been released, he begins to terrorize Bowden and his family, particularly targeting Bowden's daughter, Nancy. Initially, Cady uses his newfound knowledge of the law (learned in prison) to annoy the Bowdens, then poisons the family dog... Who's next ? Max Cady just got out of jail. He then threatens the lawyer (Sam Bowden) who defended him, arguing that he ruined Max's life sending him to prison. The threats become intelligent actions that make Bowden and his family fall in fear.
