Where was Fifield after his mutation?

Yep true that..... I figured as much that there really is no answer to some of those questionable behaviors.

I wouldn't say that there aren't answers to be found, but basically I agree the Millburn and Fifield getting lost thing was just a plot device to show how the goo works.

The goo itself is important, even though Fifield and Millburn getting lost is kinda dumb.

I kinda think Fifield and Millburn were easily manipulated..In the Spaight's script David actually says something like "you're all so stupid!" after trying to attack Shaw, "Stupid and slow" (he chases her). This is right after David reveals to Watts that he read their psych profiles.

Basically the way I rationalize Fifield and Millburn getting lost is that Weyland actually set out to hire slightly below average intelligence scientists, peole who were easily manipulated, people who would jump at the chance like Holloway, those who were in it for the money, Ford who was almost on Weyland's side, true believers, and Holloway who was childlike and eager to play with his toys etc. So he could deceive them. Or allow them to get lost themselces. Those of them Vickers hired personally, like Janek, had more survival instincts in them. At least the merc was trying to survive by keeping his gun, "see how far that gets you". Shaw might be smarter than the rest, because in the Spaight's script David mentions her IQ is actually much higher than Holloway, and Holloway was arrogant (but this was when his character was a lot diff). Watts/Shaw might have more instinct/intelligence "in her" than the rest of the crew.  Weyland was superstitious, he needed a true believer on board he could manipulate with the bigger questions. Although Shaw has her own beliefs and motives, she may be smarter than the rest, and Weyland wanted her on board even though his true agenda was all about getting immortality for himself.

I would have loved to have seen more of the Fifield monster and what he would have evolved into! They could have increased the running time of the film by 10 minutes and had the Fifield monster enter the ship by climbing up the landing gear.

Fifield ran off and later found his way to the ship because...

1) plot device

2) he retains his memory but loses control of his amygdala in the limbic system and kills those who he sees put him in this situation (like BigDave stated earlier)

I think it's a stretch for the audience to consider #2, so I would say plot device.  That being said, I'm okay with it. :-)

Yeah would have been nice to had seen more of Fifield, i think it was one bad bit of the script as Fifield i felt had killed to many of the crew...

Also orginally that was not the case in Spaights draft and Fifield mutated to something more Xeno than the Toxic Avenger look....

I undertand Ridley is no fan of CGI and felt the CGI scene did not look so good and that the actor  Sean Harris did a good job with the action scene...

But i think they could have done a CGI overlay over Harris to give us more of a Xeno esque look... but ultimately Ridley and Fox decided to tone down even more Xeno elements in the movie..

Above is the Fifield concept i liked the most, and the closest they got to production on similar was this image below.

This one i really liked, and instead they could have made a Mask that Harris wore under the Helmet and then used CGI to tidy up the shot just as they did with the Engineers to add the odd finish touches via CGI

Bigdave; That first image is brilliant! I would have loved to have seen Fifield evolve into that as the second stage and yes, Ridley's never liked CGI, he prefers to make everything by hand. However, CGI these days (if used properly,) can produce amazing results! I've always HATED the use of CGI until very recently.

Yer cgi has now got to a level were most situations it is worth it like even though the stage sets were great they could of benefited from cgi backgrounds can be made on a much grander level and I hope they use cgi for part 2s backgrounds becuase I am imagining grand things for the  home planet. Organic stuff is harder but some human faces are almost perfect but I understand they are hard to do. 

Well here is where i did not understand why Ridley said that...

As the Deacon and Engineer did get a kind of photo shop treatment via CGI, you see the actual props and costumes lacked the polish the finish movie had.

And the Sacreficial Engineer was CGI when he was being broken down.... and looked great.

I think the failings was simply time restraints and budget, you see the Fifield CGI did not look as solid a job as the other CGI work in the movie, they simply must have done CGI Fifield late on and it never looked quite as good as they hopped for. Sometimes a movie has problems when the budget and time restraints kick in.

The Thing is a pure example of this, the idea was to use Props and CGI over them to make them more polished and some scenes they did this, others they then due to time and budget went for total CGI... when the movie was working and had part finished some really awsome prop and animatronic work that was well, AMAZING....

But time and budget meant they cut them short and relied more on CGI and as that budget and time restraint got closer to the end, well they had to spend less time and money on what ever shots was left.... this is why the last CGI Thing was well, utter utter pants, and poor and damaged the movie, yet the earlier scenes was not so bad.

And again our CGI Fifield looks kind of the same not as bad, but looks like it was done with not so much time and budget left, so not as polished or good and they had no time to redo another CGI shot or to go back and work on that AWSOME Animatronic model, and so i guess they stuck with the Toxic Avenger Fifield in the end..
