... As to the gender of the Alien image, to tell the truth, the subject didn't come up. I don't even know if the 'greys' have gender as we understand it. Whitley corrected the developing image to have a certain fragility, a vulnerability.
Concerning the Alien's gender, the truth is that this topic wasn't discussed. I am unsure if the 'greys' possess a gender in the way we understand it. Whitley modified the image of the Alien to make it appear more fragile and vulnerable.
