The (or one of the) official site(s) for the J.J. Abrams-produced 1-18-08 has revealed a third photo from the movie which shows New York residents during or after the attack on the city (by what is unknown still). You can check it out at 1-18-08.com, where you can move the three photos around to get a better view. The timestamps on the photos indicate that things happen pretty darn quick.
Released by Paramount Pictures, the secret movie is directed by Matt Reeves and written by Drew Goddard. Michael Stahl-David, Odet Jasmin, Mike Vogel and Lizzy Kaplan star.
