Dreamworks has created a viral market site for the horror film sequel "The Ring 2". The site is www.7daysleft.com. Here is Adfreaks description of how the site's viral campaign works:

You enter a friend’s e-mail address and cell-phone number. The site then sends the friend an e-mail, inviting him or her to view the Ring Two trailer online. As the video plays, the friend’s cell phone rings, and a voice on the other end whispers “seven days”—which, if the friend has seen the Ring movies, might just prompt a soiling of the friend’s trousers.

This viral campaign is very interesting to me because of its use of the cell phone as the central technology. A trailer is played and then the call comes. Dreamworks is not currently doing this program in the US.

The idea is good on first sight, but if anybody would give out my email "and" my cell phone number to such a site, I really would get angry at the one who did do that.
