A new movie trailer which fails to reveal the film's title is leaving U.S. cinema audiences desperate for more information.
The strange promo, which is being shown across the country before screenings of America's number one film Transformers, features a bunch of New Yorkers enjoying a dinner party before the lights go out and fireballs drop all over the city.
The trailer contains no title, but reveals a release date of 18 January 2008 and that the movie is produced by Lost co-creator and Mission: Impossible III director J.J. Abrams.
The film is known as Cloverfield, although Hollywood studio Paramount Pictures insists that will not be the movie's title.
Take a look back at October's inaugural event.
The film is expected to continue without Mendes' involvement.
