What an interesting thread. It seems you all have stumbled on to two different threads of a game.
The first game began as a part of the five films released by BMW Films (
http://www.bmwfilms.com) beginning in early summer 2001. The five films, in chronological order of release are: Ambush, Chosen, Star, Follow, and Powder Keg, each directed by a different influential director (John Frankenheimer, Ang Lee, Guy Ritchie, Alejandro Gonzalez Inarritu), and all produced by David Fincher, himseldf a repected director. They are excellent, if you have not seen them, do so now. Contrary to several posts, this was a promotional campaign, not an in-house training series, and in fact grew to become one of the most successful online marketing campaings in history.
Also released were five very short digital films directed by Ben Younger, director of The Boiler Room. Each of these films contained a 'clue', be it a website, phone number, etc. If one were to follow these clues to their conclusion, they would lead to a time a place where you could recieve a free BMW Films DVD. I myself have one.
However, in preparation for the new series of BMW Films to be released starting on Oct. 23 (three days ago), the links began to change, beginning as far back as January of 2002. As I said, three days ago, the new film was released, directed by John Woo. In the movie, the hero, the driver, played by Clive Owens, dials a phone number to rescue the hostage. If you dial the same number, you recieve a cryptic message, and instructions to go to

I think everyone here should follow the path to the end result: the contest for the BMW Z4. If you do wish to learn the answers, simply download the movie and dial the number, or begin your search at
www.mothtotheflame.com As I have already solved the puzzle, I can help you along the way, if you like.
