The original version was considered too shocking to be released and most of those copies were destroyed. Directed and produced by Tod Browning whose career never recovered from it. Later the film was recut with several scenes removed, however it still received negatively by audiences, recording a loss of $164,000 and remained an object of extreme controversy.
