I believe this is the original image by HR giger on the basis of which he was hired to design all the alien concepts (I could be wrong). But assuming I'm not it might give you a different perspective.Gorfias said:Odd that the main corporate type appears to be a woman. The Alien movies were supposedly a metaphor for male aggression. (The Alien implants it's off-spring to a host, the off spring kill the host. The first one to burst out of John Hurt even looked like a woody.

The screenwriter actually said that he wrote the alien as a way to make rape imagery personally frightening to a male audience. Thus, I don't think the alien is male at all, I think it's deliberately ambiguous, because that makes it more unsettling. Heck, the costume was basically an elaborate dominatrix outfit with a big shiny black dildo for a head.
On topic. Seriously, can you not suspend disbelief for a minute? That stuff was the height of technology in 1979. It wasn't selected for kitschy stylistic purposes, it was just the stuff which was available.
