The main purpose of a movie trailer is to get the audience to want to see said movie, right? But normally it's an auxiliary thing, aiding a movie's awareness. Well, with Cloverfield things were a little different; the sole hook of the film was the trailer. Released before Transformers, the trailer was the perfect slow burn. Captured on a camcorder, we see a surprise party interrupted by an unexplained attack, with an earthquake making way for an explosion in the center of New York, culminating with the head of the Statue of Liberty crashing down a Manhattan street. What was this film? Every element of the trailer was dissected, with ideas ranging from Godzilla to Voltron, with throwaway lines providing the basic for grand theories. It doesn't even give the name of the freaking movie, leading to months of the monster flick being known as 1-18-08, it's release date. The whole advertising campaign was top notch, letting the fans build the hype semi-organically. On the conventional front things were very restrained, with only the debut teaser, a subsequent trailer that served to only make the film more mysterious, and single poster design depicting a headless Statue Of Liberty. An alternate reality game helped flesh out the world of the film, but at its core Cloverfield actively needed to reveal nothing to work. https://www.youtube.com/watch?v=IqQzvfn_s30 Did we miss any incredible, spoiler-free trailers?
