Corrected entry: The military's security is ridiculously inadequate. After Gort subdues the only two GIs guarding him and the spaceship, the military encases Gort in solid material, but later still only two GIs guard him and the spaceship when Patricia Neal arrives. With a development of this magnitude the US military would probably seal off the city.
Corrected entry: The man from mars knows all about our warlike attitudes. He is surrounded by army men with all kinds of weapons aimed at him. He walks out of the saucer with his helmet on which makes him look spookier and then, for a smart advanced being, he pulls the stupidest stunt he can....pulls out a device that looks threatening and snaps open. Of course he got shot....I would've shot him myself.
Corrected entry: When Klatuu is running away from the cab, the soldier shoots him in the back. When Gort brings him to the spaceship, we see blood on the left FRONT of his coat.
Corrected entry: Klaatu supposedly neutralised all the electricity on the Earth for 30 minutes, which would explain why gasoline-powered cars would stop, because the spark plugs wouldn't work. Diesel engines (used in many trucks and buses shown in the film), however, don't use sparkplugs, so they would keep running.
