In Girl, Interrupted Winona Ryder (above) plays the 17-year-old Susanna Kaysen, a highly intelligent student who was diagnosed with Borderline Personality Disorder in 1967 and spent two years in a psychiatric hospital. The film is based on Kaysen's own memoirs of that experience which were published as Girl, Interrupted in 1993 and spent 11 weeks atop the New York Times best-sellers chart. This is the third film directed by James Mangold, who made Heavy and Copland.
