I was watching the Cloverfield trailer again and I glimpsed the scene that was probably used to take the 1-18-08 photo of the faces looking up. At first I was only able to see the one girl that clearly matches the face on the left, but with Rob on the left who has some stubble hair on his face. He obviously does not match the person on the left, however there was another person that was close with the group just seconds before that does match. A girl standing slightly behind the two can be seen coming up close to the two right before they look up. At this point the camera rotates hiding the girl from the trailer shot of them looking up, but it puts her in the perfect position to pose for the website photo. An image of the scene right before they look up is seen below (this sequence of events can be seen starting at the 1:27 mark of the trailer):
