Before the movie 'The Ring' was released, the previews all showed the killer tape and no title. My brother's friend (named Noah, LOL!) went to a concert by a local group where he picked up a blank video box with a un-named video inside. Being adventurous, he went home and decided to watch it sense everyone was asleep, just incase it was a porno. inside, he found a website address labeled www.anopenletter. Noah watched the movie and it was the same as the killer tape in 'The Ring'. Feeling comletely disturbed, Noah decided to visit the website and it ended up being a blog site about a man who described himself as a paedophile, and had watched the tape and had recieved a warning saying he would die in seven days, and that he found another series of websites inside the first one, and finally, after a few hourse, stumbled across...
'The Ring' official site. I don't know it it's true, the story i mean, but I found proof that such things DID occur before the release of the US version of the Ring, here are some describing the events from IMDb.com:
To promote this film the studio placed copies of the mysterious "killer tape" at concerts and events. The tape had a label directing whoever watched it to a web site (www.anopenletter.com) supposedly written by a pedophile who'd seen the tape and was now trying to warn others about his impending fate (this was the character portrayed by Chris Cooper in a sub-plot deleted from the theatrical release). The website contained links that led to other movie-related mock-ups, including a page written by one of Katie's friends who was unaware of Katie's death and believed she'd been kidnapped or run away, and a page written by scientists who researched psychic phenomena involving television transmissions. When the movie was released, Dreamworks deleted all the Web pages and denied ever having anything to do with them.
You can find that and other crap about the movie from IMDb.com! What an evil thing to do to promote a movie...[;)]
