The scene in which Carol encounters the disemboweled dogs in the clinic became quite controversial because of the startlingly realistic (and graphic) appearance of the fake prop dogs. Director Lucio Fulci was nearly sent to prison because it was believed that the dogs were real and Fulci had allowed animal cruelty on the film. However crew members were able to testify in court that the "dogs" were indeed fake and no animals had ever been harmed. Special effects artist Carlo Rambaldi even presented the dog props in court to convince the jury. This was the first time that an effects artist had to testify in court that their work was fake.
