Citizen Kane (1941)
When newspaper magnate Charles Foster Kane dies, a reporter tries to unravel the mystery of his last word: "Rosebud." Orson Welles' film debut – made when he was just 25 – pioneered new techniques in directing and showcased a bravura performance from a young Welles in the title role. But it also enraged real-life publisher William Randolph Hearst, who believed that Kane was based on him. Hearst's efforts to suppress Citizen Kane meant that the movie only became recognised for the classic it is many years later.
