ALIEN TRILOGY

 In Alien 3 , the Alien got a complete redesign, as it should, since it was to be a different type of a creature, but that design will define alien look for many movies to come. For example, the shape and look of the ribcage, the digitigrade legs and the hip bones designed for Alien 3 will remain in every alien design after that movie. Alien 3 was also the first time the Alien creature has been stripped of all of its biomechanicality, which would never fully return to the creature ever again, leaving only the first two films with biomechanoid Aliens.  The creature in Alien 3 was always suppose to be coming out of an animal and be different than the ones in the first two movies, which was a fantastic idea to do something different but not different too much - it's simply another alien, but this time more ferocious and different looking because it comes out of an animal, and the aliens draw from their host's DNA - an idea going back all the way to the 70's.  Ridley Scott...
