Project Cloverfield a.k.a The JJ Abrams trailer before Transformers starts.

Hmm.

Spoiler:

In the top sketch, he has 4 big legs, but in the bottom sketch, he has 6, and his neck is more extended. Also, the sketch doesn't show the 'air sacs' on the side of its neck like paco mentioned. Although, it does look similar to the 'concept art' posted earlier.

Jam it back in, in the dark.

Spoiler:

In response to the gif just posted:
1. That creature looks way too mobile for something that's supposed to be huge.
2. Why would it go through the effort of eating one little camera man?
3. Maybe it's one of the creature's spawns? Like something that grew from someone, like we saw that 'expanding' girl in the trailer.

Or, or or or or or.... I could just fucking wait for the movie to come out already. :\

There's nowhere I can't reach.
