Alien looks identical to the one in the bogus Santilli films... distended belly, bulbous head, thick body, female pubic cleft, wounded leg, gaping mouth... could even be the "missing" footage Santilli said was so badly damaged he "reshot it" (ahem!). Hard to see all these things in the screen snaps here, but in the film you can, fairly well. It appears to be the pre-autopsy shots of the body first being brought into the hanger with all the officers swarming about.
This still is from a minute or so of footage that appears near the end of the Ray Santilli produced comedy film about the AA. See my site:
