Wow! If you wait long enough!
"Alien Invasion using Dead Human Bodies"
I guess its true... If you wait long enough, you may just see movies based on ideas you have had! -- In MY version, the Aliens had hovering, frisbee-like "RobotBrains" that drilled away the top of dead people's skulls, in order to replace the brain in controlling their bodies. The Aliens found the drawbacks of using dead humans were "rigor mortis" and the rotting stench, which warned everyone which direction they were coming, or where they were (depending on wind direction). I foresaw it would be cheap in the props dept., just zombies, with metal "hats".
It will still be interesting to see these guys do with the concept.
