January 17, 2012I don't know about the Comic-con trailer, but there were brief shots in the leaked teaser trailer that didn't make the official version. I brought them up in a new topic I titled, "The Forest Through The Trees', but here's an excerpt that might bring light to your question:
"When the official version of the teaser trailer hit, I poured over it endlessly, as I’m sure all of you did, and I noticed something or rather its absence…Two shots, one second apart that could originally be seen in the leaked version of the trailer that appeared over Thanksgiving weekend. They are both particularly interesting in spite of their poor quality.
The first, at :37 sec, shows a black skeletal hand, perhaps it’s not a hand, but something moving over the edge of a cryo-unit. What it is or isn’t, I don't know, but am very curious about. It’s alive, it’s moving and it sure as hell does not look human.
The second, at :39 sec, is of a bulge moving in someon'es stomach. It, again, looks very strange and appears for less than a second, so it’s rather difficult to hazard a guess at what it might be.
These shots flank, before and after, a shot of the SpaceJockey chair rising out of the floor, as appears in the official trailer."
The leaked trailer is still available at: http://www.disclose.tv/action/viewvideo/83539/PROMETHEUS_Leaked_Trailer_Enhanced_De_noised/
The second of the two shots might be what your referring to, but I only may have seen it wrong, concidering the quality is so poor. Check it out and tell me what you think.
