 A Behind The Scenes still from the Extended Version of the Ultimate  DVD boxed set indicates George A. Romero (I) (qv) had a third  cameo in the picture. The still shows the director standing to the  side of the camera, his sleeve rolled up, holding a pistol upwards.  Behind him a part of the mall can clearly be seen, indicating it was  shot on site. Near the end of the picture, a similar shot exists: a  POV from a man holding a pistol firing up past a fenced in area on  the upper floor where Peter is running across.
