In Totentanz (Urban Gad, 1912), Asta Nielsen plays a guitarist-dancer who must take to the stage to support her infirm husband. She attracts the devotion of a composer, and soon she feels attracted to him. Torn between desire and duty, she snaps during a rehearsal of his latest piece, “Totentanz.” In a chilling gesture, she uses his dagger to slice her lute strings. Soon the two are locked in a violent erotic struggle, and a stabbing ensues. In all, melodrama as ripe as one could want. —http://www.davidbordwell.net
