Copies of the "Cursed Tape" were dropped in public places as a form of promotion. After about five minutes of footage, the viewer is directed to the movie's website.
According to the production notes, there were bizarre incidents on set of life reflecting art. On the seventh day, the production office was discovered to have flooded overnight, the result of a burst water pipe. Water is a strong theme in the film. In response, director 'Hideo Nakata' requested a Japanese purification ceremony be carried out by a Shinto minister, but the strange incidents continued. While on location, a swarm of thousands of bees descended on the prop truck, prompting the immediate evacuation of the department, before the bees left as quick as they arrived. For no apparent reason, a five-gallon water jug burst open in the production office kitchen, one again flooding the same room that had flooded only weeks earlier. One morning on the Universal lot, a set costumer stepped out of the parking garage to discover an antlered buck charging across the asphalt in her direction. Though deer are a regular occurrence in the hills, the similarity to the deer attack in the film is uncanny.
