Sybil (1976)

Although not a feature film, Sybil deserves the final spot on this list for its accurate depiction of multiple personality disorder and dissociative identity disorder. Based on a true story, the Golden Globe-nominated and Emmy-winning miniseries profiles a young woman named Sybil (Sally Field) who created multiple personalities for herself after suffering years of abuse at the hands of her domineering mother. It's a powerful and compelling miniseries that sparked a much-needed conversation about the treatment of mental health issues on screen.
