GamesRadar - You know how the original Alien in the original Alien has a human skull visible underneath the front of its transparent exo-head? No, don’t worry, hardly anyone does. Due to the way that Ridley Scott lit the beast in the first film, it never showed up. Backlighting = silhouettes = no visible sign of the costume makers’--or even designer H.R. Giger’s--original intent. Thus, the human skull was written out of later Alien visual canon, replaced by the standard black, eyeless, penis-dome we all know today. Until that is, Creative Assembly started designing their xenomorph for Alien: Isolation.
