Production-made Xenomorph alien head created for Alien vs. Predator: Requiem from 2007. This Xenomorph head features many special effects functions that were used on set to give the animal life. By means of electronic and pneumatic devices the jaw could open and close, the lips could snarl, the inner jaw could snap out and its tiny jaw could also open. The functionality of these devices have not been tested. The upper skull and jaw areas are made of fiberglass and the neck area is made of foam rubber. The neck has snaps and zippers used to attach the head to a costume. The lips have wire armatures inside and are covered in rubber. The entire head is painted black and heavily washed in silver paint. There is a series of wires and pneumatic tubes protruding from the bottom of the head and there is a magnetic door in the lower rear of the head where additional wires are accessible. The head comes mounted on a metal and wooden display stand. The head and stand together measure approximately 34.75 x 21.5 x 12 inches.
