You know: The one that's been playing in front of "Transformers"...the one featuring a mysterious alien attack that's being hyped by a handful of teaser websites and (most potently) a veil of secrecy by the filmmakers.

I saw the teaser last Tuesday. It's the one where a bunch of teens are partying before New York goes kerplooey in the distance. All I really got out of the teaser was this: 1. The movie opens January 18th. 2. It looks like "The Blair Witch Project" meets the new-fangled "Godzilla." 3. I wanna see it. Of course.

The project's presently being called "Cloverfield," although that's not the real title. IMDb just got around to adding the J.J. Abrams production recently ... because I searched for it last week and it definitely wasn't there.

According to The Hollywood Reporter, the "Cloverfield" project began filming in New York in June and has a budget of $30 million. The report also names the first few castmembers: Michael Stahl-David from "The Black Donnellys", Mike Vogel of "Supercross," Lizzy Caplan (Janis from "Mean Girls"), and Odet Jasmin.

Give it up to Paramount and J.J. Abrams for keeping this project "hush-hush," but here's what we know for sure: It's being directed by "Felicity" producer Matt Reeves and written by "Alias" scribe Drew Goddard. The thing will be done entirely with handheld cameras ... and yes, it's a monster movie.

But the clever marketing doesn't end with a mysterious trailer, oh no. There's also a puzzle-filled website called EthanHaasWasRight.com, and ... man, I'm getting confused already. I just wanna see the movie.

Check out all the "Cloverfield" mysteries at the teaser site, EthanHaasWasRight.com, and the freaky counter-blog Ethan Haas Was Wrong. (If you get stuck on the puzzles, Film Ick and Slash Film have helpful threads from other aspiring detectives.)

And while you're at it, let us know what the secret of the island is on Abrams' other brain-twister.
