The making of visual effects for Cloverfield. In the second video: “Subway Parasites” segment from the Cloverfield DVD’s “Cloverfield Visual Effects” extra. This 2008 disaster/monster “mockumentary” was directed by Matt Reeves, produced by J. J. Abrams and written by Drew Goddard.

The film follows six New Yorkers attending a party on the night that a gigantic monster of unknown origin attacks the city. All footage is shot from the perspective of the (fictional) handheld cameras carried by the characters, who film the action as the events unfold. 

The careful replication of the New York cityscape, as it’s destroyed by the massive Godzilla-like monster, was impressive for its complexity and accuracy.

Visual and computer generated effects were produced by Double Negative and Tippett Studio.
