EYE Film Institute Netherlands

Based on the look of the film (clothing, interior etc.) and because of the (identified) films from the same party of films dating from this period we think the film is from around 1916 (give or take a few years).
Could the girl playing Hanni be Hanni Weisse?

According to the main intertitle cited above, this is DIE SCHWARZE GEFAHR, a German film starring Lia (or Lya) Ley, made in 1918. The young woman wearing a dark dress (frame 1) looks like Lia Ley. The film is registered in the German Early Cinema Database. The main actress is not mentioned there, but you can find her name in newspaper advertisements. The smiling actor in the middle of frame 5 is Rolf Brunner who often co-starred with Lia Ley.
