"Yeah, I had an idea to make a very scary movie, based on a kind of serial murderer that preys on tourists"

This quote by Brian De Palma recommends that he had an idea to develop a scary movie based upon a serial murderer that specifically targets tourists. This might be interpreted as a commentary on the threats of travelling to unknown places, as travelers are typically viewed as easy targets for criminals. It might also be seen as an alerting to travelers to be knowledgeable about their environments and to take extra preventative measures when travelling. De Palma's quote could likewise be translated as a reflection on the scary genre, as it suggests that he wanted to develop a movie that would be especially frightening. By concentrating on a serial murderer that preys on tourists, De Palma might be trying to produce a motion picture that would be more extreme and suspenseful than other horror films.
