No prints of this film (Alfred Hitchcock's second)
are known to have survived and no one has seen it since the late 1920s.
The filming of exteriors in Austria was delayed by heavy
snow. A local fire brigade was finally persuaded to use their manual
pump to wash the snow off a group of houses and the street nearby.
Nita Naldi fainted from exhaustion at one point during
filming. She recovered almost immediately and merely complained that
the floor was too hard.
