In one street scene shot in downtown Phoenix, Christmas decorations were discovered to be visible; rather than re-shoot the footage, Hitchcock chose to add a graphic to the opening scene marking the date as "Friday, December the Eleventh".
U sceni koja je bila snimljena u središtu Phoenixa naknadno je utvrđeno da se vide Božićni ukrasi u pozadini pa umjesto da scenu snimi ponovno, Hitchcock je odlučio u uvodnoj sceni dodati vrijeme radnje: "Petak, dvanaesti prosinca".
