I was twice shown a B/W movie in jr. high school social studies where it featured scenes of gruesome slaughterhouse activities set to the tune of "Blue Danube". The movies were shown numerous times in this school in the early1970s but easily date back to pre-World War II or more. I have been challenged to produce someone who has seen this movie or (better yet) some traceable source detail of the movie. Date, title, producer, studio. Anyone have anything??

Hi Crustigears - what school district?
