The egg chamber of the alien where John Hurt as Kane comes into contact with the Facehugger was constructed in the Acton Lane Power Station here which no longer exists.
Description
A large egg-shaped object that is cracked and emits a yellow-ish light hovers in mid-air against a black background and above a waffle-like floor. The title "ALIEN" appears in block letters above the egg, and just below it in smaller type appears the tagline "in space no one can hear you scream".[1]
