I really like both alternate Fifield designs we've seen, and I think I would've personally preferred the one shown in Cinefex - but I can also see why they didn't pull the trigger on either. Both (the other being the "frowny face" model we've seen, which was utterly alien, not human at all) risked being laughed at by a post-mod audience as being sort of "evil E.T." I would've done it with this one, but I was fine with the monster we got. I just wish they'd run the scene a bit longer.
