 In one scene at a train station, Buster Keaton (qv) was hanging  off of a tube connected to a water basin. The water poured out and  washed him on to the track, fracturing his neck nearly to the point  of breaking it. This footage appears in the released film. Keaton  suffered from blinding migraines for years after making this movie  and was unaware of the reason, until a doctor diagnosed him in the  1930s.
