Ironic as during the teaser trailer on AVPGALAXY News feed I almost commented "looks like Robot Chicken" and low and behold it is.
Robot Chicken had done tons of ALIENS, PREDATOR and AVP stop motion parodies during it's, many, series runs. YouTube it.
Don't believe the "background story" of this particular parody, I just think Robot Chicken is so widespread 20th Century Fox did a "thow everything and the kitchen sink" approach into damage limitation, including a very early home release (US only).
