io9.com, the usual source for everything scifi, TV & science related has posted up a interesting video that has to do with the visual effects behind Cloverfield.  Its not anytype of documentary or featurette, but a soundless comparison of scenes and what they actuallylooked like without the visual effects.  It actually shows how well done the CGI was in this film, because most of it looked flawless.  What looks like the city is actually just a big green screen and of course the Statue of Liberty head was green screen... you didn't actually think they tossed a gigantic head down a street now, did ya!?!

Anyways, take a look and head over to io9.com
