Maria Schell
Maria Schell's last years were overshadowed by her ill health. She attempted suicide in 1991 and suffered repeated strokes.
Her final public appearance was at the premiere of her brother Maximilian's documentary film, "My Sister Maria" (2002) on her life; both were awarded the Bambi Award for their work.
