Hello Alien fans!
I've made a video explaining in details how David created Alien (or rather proto version of xenomorph).
In it you will find answers to many questions, including:
How were the cocoons created in his basement? Step-by-step instruction.
What animal became the progenitor of the facehugger? Where did David get his inspiration?
How does the alien see and why does he have an elongated head?
What happened to Elizabeth Shaw?
And much more. I did my best and will be glad to see your comments.
