"In "The Blue Planet" (2001) (mini), David Attenborough said the 'Alien' monster was modeled after the Phronima, a creature spotted by submersibles at great depths. It's only an inch long, mostly transparent, and it looks like a shrimp with head, eyes, jaws and teeth just like the H.R. Giger monster." If you are interested in the movie "Alien" and don't know about IMDB.com and/or it's trivia pages, check out the link above. This is cut-and-paste from the IMDB trivia page for "Alien". I notice that it never actually comes out and says that the monster was based on Phronima, but hopefully David Attenborough did his research before making a statement like that. =) "The original design for the Alien by H.R. Giger had eyes, which were eliminated to make the creature look even more menacing." This is another interesting tidbit from the IMDB page. "The engine plasma that blasts the alien away from the shuttle at the end of the movie is actually just tons of water pouring over the camera." ...and another one. =)
