German actress Brigitte Helm (1906-1996) is a legend
because of her dual role as the noble Maria and as her evil double,
the robot Maria, in the silent science-fiction classic Metropolis (1927, Fritz Lang).
After Metropolis she made a string of over 30 films in which
she almost always had the starring role.
Helm easily made the transition to sound films, before she abruptly retired in 1935.
