In theatres, this film was preceded by the following titles: "A warning to vandals and hoodlums! This theatre is reserved for people who came to watch and enjoy the show. If you engage in any destructive acts or noisy conduct, we don't want you here! You'll not only be asked to leave, if your actions justify it, you will be prosecuted. Remember this warning and guide yourselves accordingly. (a) The Management."
