Well, from the pieces that I have (theatrical cut, promo material, deleted scenes) , I dont think any unanswered questions will change, Im trying hard to nip/tuck out headscratching moments, like the death of the biologist and geologist, and lines like "god does not build in straight lines", "DNA MATCH" and whathaveyou..
.
Im not a scientist, but I believe a 90% match woudve been enough, and waking up to find the bio/geologist offline, seems creepier then seeing the wonderful practical/cgi effects of the penis/vagina snake aptly called the 'hammerpede'

my whole goal is to build more tension in the film and make it MORE of a mirror of Alien, then the theatrical edition was.

Basically as an intro to the alien franchise, even with Prometheus' eventual sequel, I wanted this edit to better set up the world run by wayland industries. A world fueled with ego and ambition, and I wanted to re-insert a little bit of AWE into the film.

Theres little to no awe of starting the movie with the engineers, then jumping to Scotland to introduce our main characters.... David, and by proxy Wayland were always our main characters, Shaw is just a true believer who survives. By building a better world and showing that this is a more slow burn sci-fi that gets creepy by minute 45, and action-y by an hour and 15, lets us settle into our seat, and start asking questions later in the film, rather then from the credits sequence.

David's line "remarkably human" now holds some weight to it, and we as an audience hopefully will unravel this film about creator/creation relationships.
