Here are some things I'm seeing in the america full trailer that was just released on saturday at wondercon. Many of these have been talked about earlier in the thread but I just want to try and provide some visual feedback with some simple photoshop annotation:
First: I must have been missing it or maybe it is just self evident but I think it's interesting that david is obviously being infected and bleeding in that close-up in-helmet screaming shot we keep seeing:
Second: while I agree what people are saying about multiple tendrils in the close up shot of Noomi, it is clear that she is having a very chestburster-shaped creature w/ one long tail removed from her by the 'auto-doc' medical device. Please also note all of the "blood-to-mud" mpaa digital fixes to make the blood look black in the trailer. In the feature they drops all over the glass and Noomi's abdomen will likely be very red and bloody:
here is my messy breakdown:
Third: it is clear that what others are saying is true: She is stapled back up by the 'auto-doc' and is stumbling down the hallway to warn the people in the mess-hall:
Forth: I believe that we clearly see the tall bald blue engineer character (whoever he may be) first activating the jockey chair navigation-gun here:
and then climbing into the chair and being instantly engulfed in the bio-mechanical flight/navigation suit that we know as the space jockey. Notice first that in movement we can clearly see a partially visible form under the articulated shoulder pads and outer ribs. Notice secondly that the inner ribs have the same sculptural patterns with one of hte many flute-like holes along his chest. Also there is a similar 'inverted' ribbing pattern on the revealed upper arm that has a lot in common with what we see on his thighs in the previous shot:
That's it!
