The first Alien design by HR Giger was I think the most successful,tall and slender the creatures head was domed by a milky translucent cover,in the film hints of the ridges underneath can be seen and stills from behind the scenes show an almost human skull with eye sockets.The hands and feet are notable for there human appearance and the creature is clearly a biped.
|The mouth / jaw hinge is covered with detail,hands are fused but human|
|Slick black design,Stan Winston added his own touch with the hands|
|Alien 3's creature despite being more animal has a more human mouth shape|
Alien vs Predator seemed to follow this alien design closely (apparently the heads were simply repainted) but the film was so dark that most of the details were hidden.
|Not only does the Alien 4 have new feet it now also spits acid..and the 'newborn"...|
