In Alien Resurrection, Ron Pearlman was up on a scaffold holding his knife to aim it's drop into the wheelchair guy's leg. After the knife stuck into his leg, Pearlman started acting like an ape/caveman or something of that visual movement. This was the exact same scene he portrayed in the movie Quest For Fire where he played a caveman up on a cliff aiming a rock to drop on another unfortunate caveman's head as a practical joke. When the rock found it's mark, Pearlman did the same performance of primate glee as he did in Alien Resurrection. I would be willing to bet Pearlman suggested to the AR director to allow him to do that as homage to Quest for Fire. (btw, I didn't catch that little connection gem, an imdb member did).
Anyone know of any homages the Alien, Predator, or AVP movies had, please serve up any other connections to movies that were not within these series. We all know the Alien and Predator series have homages within their universe like the skinned bodies and alien trophy skull, etc. I am looking for A/P movie revealing homages to no A/P movies. I love these type of little factoids and want to know if there are more.
