"Citizen Kane," directed by and starring Orson Welles, is a 1941 film that follows the rise and fall of newspaper tycoon Charles Foster Kane, inspired by the life of William Randolph Hearst. The film's narrative structure is non-linear, unfolding through flashbacks as a reporter investigates Kane's dying word, "Rosebud". Welles utilizes innovative techniques like deep-focus photography, low-angle shots, and a fragmented narrative to explore themes of ambition, wealth, power, and the corrupting influence of both.
