Of course, the idea of humans enslaved by machines in all three Matrix movies owes a huge debt to The Terminator, but even the visuals here borrow shamelessly from Cameron, particularly the Armored Personnel Units — the lumbering, robotic exoskeletons worn by the Zion soldiers seem inspired by the similar apparatus Sigourney Weaver uses to fight the creature at the end of Aliens.
We cut from soldiers fighting in big Aliens rip-off machines, to a couple of chicks trying to shoot missiles into the center of the Death Star, or whatever that big drill thing is, to a ship being manually piloted by Niobe (Jada Pinkett Smith) -- with an uncharacteristically stressed out Morpheus (Laurence Fishburne) in the passenger seat -- making its way back to Zion.
Having said their peace about quantum physics and bending spoons already, homage is paid to sci-fi classics while showcasing all the best in today's jaw-dropping special effects: Ripley's power loader 'mech' from "Aliens," the gun turret / Death Star escape sequence on board the Millennium Falcon from the from the original "Star Wars," and even a bit of "Starship Troopers."
The APU battle bots the Zions use look like they were taken straight from the dock movers in Aliens with all the clunky vulnerabilities that implies.
