"DIE, YOU ALIEN SHITHEAD! [Prepares to shoot, but a Martian notices him] Uh-oh. [Drops his gun and holds up a flag] I surrender! [The Martian disintegrates him with a ray gun]"

"[About to get on the bus to leave for the Army, to his brother, Richie] So long, retard."

"[Making one last appeal to the Martians] Why... are you doing this? Why? Isn't the universe big enough... for both of us? What is wrong with you people? We could work together. Why be enemies? Because we're different? Is that why? Think of the things that we could do. Think how strong we would be! Earth... and Mars... together. There is nothing that we could not accomplish. Think about it! Think about it. Why destroy... when you can create? We can have it all, or we can smash it all! Why can't we... work out our differences? Why can't we... work things out? Little people... why can't we all just... get along? [The Martian Leader sheds a single tear. Dale smiles to himself, impressed. The Martian Leader approaches him and shakes hands with Dale. Then, the Martian Leader's hand detaches from his arm] What's this? [The hand proceeds to crawl all over Dale's body. At the small of his back, it stabs through his body. Dale collapses to the ground, dead. From his dead body, a flag rises: a Martian flag]"

"[Overhearing the Martians' destruction of France via telephone] ...mon Dieu.."

"Rest assured that we will soon come out at a very real... outcome."

"I want the people to know that they still have two out of three branches of the government working for them, and that ain't bad! I want the people to know that the schools will still be open, okay? And I want the people to know that the garbage will still be carried out. And I want a cop on every corner - which, incidentally, we would already have, if they had listened to me in the last election!"

"Don't run! We are your friends!"

"We come in peace! We come in peace!"

"All green of skin... 800 centuries ago, their bodily fluids include the birth of half-breeds. For the fundamental truth self-determination of the cosmos, for dark is the suede that mows like a harvest. [General Decker: What the hell does that mean?!]"

"[Watching Martians massacre the Senate] Guess it wasn't the dove."

"I'll tell you one thing, they ain't gettin' the TV."

"I'm not a crook, I'm ambitious. There's a difference."

"I'd been thinkin' about Mars when there wasn't no Mars."

"Narrator:: The heavens. Once an object of superstition, awe, and fear. Now a vast region for growing knowledge. The distance of Venus, the atmosphere of Mars, the size of Jupiter, and the speed of Mercury. All this and more we know. But their greatest mystery the heavens have kept a secret. What sort of life, if any, inhabits these other planets? Human life, like ours? Or life extremely lower in the scale? Or dangerously higher? Seeking the answer to this timeless question, forever seeking, is the constant preoccupation of scientists everywhere. Scientists famous and unknown. Scientists in great universities and in modest homes. Scientists of all ages."

"[opening narration] This was the planet Mars as my crew and I first saw it. Dangerous, treacherous, alive with something we came to know only as Death. This is what we faced when our spaceship cracked up and landed just six months ago in January of this year, 1973. But it seems as if six centuries passed before rescue ship arrived. For today of all my crew, I, Col. Edward Carruthers of the United States Base Command, am the only one alive. Now I will be going back to face my superiors on Earth. In Washington. And perhaps there, too, I will find another kind of death."

"[telling his story to Ann] We were all outside the ship exploring the southern tip of syrtis major. Suddenly a sandstorm came up and we started back. I was driving the jeep. Sand was so thick we could barely see. We were almost back to the ship when Cartwright just disappeared. One minute he was there and the next minute he was gone as if something had just plucked him out of the jeep like... candy out of a box."

"So I decided after one bad marriage to bury myself in science."

"There's only one kind of a monster that uses bullets."

"Ladies and gentlemen of the press: As you know, the first attempt to send a spaceship to the planet Mars was made six months ago. We knew that that ship, the Challenge 141, had reached its destination, but that's all we knew. Teleradio communication with Mars ceased immediately and we were forced to assume that the ship and crew had been lost. The man in charge of this expedition was a man who had become known to the world as the first man to be shot into space, the man who pioneered interplanetary space travel - Col. Edward Carruthers. Two months ago, we sent a second ship to Mars to learn the fate of Col. Carruthers and his crew. The President has asked me to pass onto you this significant news: Col. Edward Carruthers has been found alive on Mars. But there's a tragic side to this history-making event: Col. Carruthers was the sole survivor of this first expedition. One hour ago we received a teleradio communication from Col. Van Heusen, commander of the second spaceship. This ship is now ready to take off for its return trip to the Earth from Mars, and Col. Carruthers is being brought back for a court martial, to face trial for the murders of the rest of the crew."

"You have been called here again to receive further information about the story which you didn't hear last night. I will read you the text of a teleradio message received from the Challenge 142 less than an hour ago: "This is Eric Royce talking. Of the 19 men and women who have set foot upon the planet Mars, six will return. There's no longer a question of murder but of an alien, an elemental life force, a planet so cruel, so hostile, that Man may find it necessary to bypass it in his endeavor to explore and understand the universe. Another name for Mars is Death"."

"Lt. James Calder: Mars is almost as big as Texas. Maybe it's got monsters."

"Eric Royce: It has to kill us or starve and we've got to kill it or die."

"Mary Royce: Every bone in his body must be broken, but I'm not sure that's what killed him. That shriveled up effect, it... I'll have to do an autopsy."

"It Breathes. It Hunts. It Kills!"

"IT! ... Reaches through space! ... Scoops up men and women! ... Gorges on blood!"

"The revelation shocker of things to come!"
