 The film was originally shown to the BBFC in an unfinished version.  They recommended that a sequence featuring a man sucking excrement  from the anus of a live rabbit would need to be removed before the  film could be classified 18. This cut was requested on the grounds  of an infringement of the Cinematograph Films (Animals) Act 1937.  When the finished version was submitted, this sequence had been  deleted and the film was passed 18 without further cuts.
