Man, I was hoping someone had created a thread about this already. I have to admit, that although Transformers was the highlight of that evening, this trailer left quite an impression on me. I had no idea it could be found on the web, I'm so glad you posted that link.
Has anyone checked out the promotional websites for this movie?

SLUSHO!

If you go to the Slusho.jp website, you can read the history of the drink. I think its a major clue as to what the monster can be. In the trailer, the moan sounds like a whale, while one man shouts (in the street sequence) that he saw "it" and that it looked like a "huge"..."lion".

A few days ago, some folks said the ethan haas website ( Ethan Haas Was Right - Look to the stars for help )
was related to the movie. I looked into it and although I cannot view the ethan hass website, I've been told it has some H.P. Lovecraft puzzles which leads me to believe that the giant monster of this movie could possibly be inspired by (if not the) Cthulhu.

But more recently, Harry Knowles of Aint it Cool News recieved an e-mail from J.J. Abrams stating that the Haas websites have nothing to do with the movie. Now I don't know how true that is, but if so, my over active imagination made some crazy connection between the Haas website and the movie.

Anywho, that's all I have.

[edit] Um yeah, I went a little overboard with the H.P. Lovecraft stuff and the EthanHaaswasright website. It is not related to the movie.

But the other two I provided are. So everyone interested, do some sluething! There are probably other sites out there.
