George A. Romero (now deceased) director of NOTLD admitted once the 1960's film 'Last man on Earth' (starring Vincent Price) was inspiration for Romero's own legendary film. But was this movie here also inspiration? Sure seems it. Especially the all-action fight at the climax.

PS That fight was sure scripted to be uneven. A soldier threw grenades right at the robotic zombies coming upon the troops and nothing happens to the robots save for mior powder burns! At the very least an arm or two should have blown off!
