Evidence 1: When Charlie shoots his good neighbor Peter Van Horn, which he thought was a monster. "How was I supposed to know he wasn't a monster or something?!"
Theme: Things may never seem the way they look
In the teleplay "The monsters are due on Maple Street" by Ron Serling, one of the main themes is "Things may never seem the way they look". What this means is that sometimes, what things look like, doesn't paint the whole image of someone's or something's character. How do I know that the theme is "Things may never seem the way they look"? Well in page , in the teleplay version of Monsters are due on Maple Street, it shows that Tommy sees a dark figure walking toward the crowd of neighbors. What happens, is that Charlie takes hold of the rifle, and ends up killing his good neighbor Peter Van Horn. (looks around at the circle of faces, his eyes frightened, his face contorted). But . . . but I didn't know who he was. I certainly didn't he was. He comes walking' out of the darkness-how am I supposed to know who he was?" The second reason why the theme is "Things may never seem what they look", is in the teleplay of Monsters are due on Maple Street, on page 75. In this scene, the people of Maple Street start to become crazy as they constantly see each others house go on and off; until we find out there were others, that were controlling the whole thing. "The people shout, accuse, scream. The camera tilts back and forth. We see panic stricken faces in close-up and tilting shots of houses as the lights go on and off. The camera continues to move away until we dissolve to a shot of the metal side of a spacecraft, which sits shrouded in darkness. Two figures silhouetted against the bright lights appear." The last reason why the theme is "Things may never seem the way they look", is in page 86. In this scene, Figure One and Figure Two discuss about the plan too destroying all human kind.(Making the humans attack themselves, so all the aliens have to do is sit back and watch). "With few variations. They pick the most dangerous enemy they can find . . .and it's themselves. And all we need do is sit back. . . and watch". In conclusion, the writer really seemed to kind of express a lesson to be thought of. "There are weapons that are simply thoughts,attitudes, prejudices-to be found only in the minds of men. For the record,prejudices can kill and suspicion can destroy and a thoughtless, frightened search for a scapegoat has a fallout all of its own for the children . . . the children yet unborn."(Ron Sterling) Basically, the mind and the vision of what we see, or believe, can actually be quite a dangerous weapon, that can change a whole you! That is why you need too use your mind wisely, as for "things may never seem the way they look".
Evidence 2: When the whole town starts to become chauos... and madness. Lights keep on turning off and on in each house, making everyone crazy and terrified. Until they couldn't take it, that they started to kill each other.
Evidence 3: When figure one explained to figure two, that it needs to repeat this pattern, in order for the citizens of Maple Street, to kill and destroy themselves, without even doing much work! (We finally understand, that even though the Aliens are causing this whole argument, it's the people of Maple street that are being the monsters of themselves.
