"Shane contains something more than the beauty and the grandeur of the mountains and plains, drenched by the brilliant Western sunshine and the violent, torrential, black-browed rains. It contains a tremendous comprehension of the bitterness and passion of the feuds that existed between the new homesteaders and the cattlemen on the open range. It contains a disturbing revelation of the savagery that prevailed in the hearts of the old gun-fighters, who were simply legal killers under the frontier code. And it also contains a very wonderful understanding of the spirit of a little boy amid all the tensions and excitements and adventures of a frontier home."

"Alfred Hitchcock strikes the highest note of suspense the screen has yet achieved!"

"A little knowledge can be a deadly thing!"

"[to Drayton] You have muddled everything from the start, taking that child with you from Marrakesh. Don't you realize that Americans dislike having their children stolen?"

"[dying] A man... a statesman... is to be killed... assassinated in London. Soon... very soon. Tell them in London... tell them to try Ambrose Chapel..."

"[to Louis] If you ever get hungry, our garden back home is full of snails. We tried everything to get rid of them. We never thought of a Frenchman!"

"Sorry we were gone so long, but we had to pick up Hank!"

"Almost beyond the imagination... A strange adventure into the unknown! [UK theatrical]"

"Moment by moment the terror mounts!"

"Hour by hour he gets smaller and smaller!"

"The Most Incredible Story Ever!"

"A fascinating adventure into the unknown!"

"Victim of weird mist ! Day by day he shrinks! Science is baffled! Cat becomes monster! Terror at every turn! Deadly attacks! Lost in a flood's fury!"

"I was continuing to shrink, to become... what? The infinitesimal? What was I? Still a human being? Or was I the man of the future? If there were other bursts of radiation, other clouds drifting across seas and continents, would other beings follow me into this vast new world? So close — the infinitesimal and the infinite. But suddenly, I knew they were really the two ends of the same concept. The unbelievably small and the unbelievably vast eventually meet — like the closing of a gigantic circle. I looked up, as if somehow I would grasp the heavens. The universe, worlds beyond number, God's silver tapestry spread across the night. And in that moment, I knew the answer to the riddle of the infinite. I had thought in terms of man's own limited dimension. I had presumed upon nature. That existence begins and ends in man's conception, not nature's. And I felt my body dwindling, melting, becoming nothing. My fears melted away. And in their place came acceptance. All this vast majesty of creation, it had to mean something. And then I meant something, too. Yes, smaller than the smallest, I meant something, too. To God, there is no zero. I still exist!"

"A strange calm possessed me. I thought more clearly than I had ever thought before — as if my mind were bathed in a brilliant light. I recognized that part of my illness was rooted in hunger, and I remembered the food on the shelf, the cake threaded with spider web. I no longer felt hatred for the spider. Like myself it struggled blindly for the means to live."

"My prison, almost as far as I could see, a gray friendless area of space and time, and I resolved that as man had dominated the world of the sun, so I would dominate my world."

"I wanted, at the time, to have the story structure follow the book, in which you would go to flashbacks, but they didn't want to do that, and accordingly, I think the first part of the film is the dullest. I tried to write my novel that way originally, interestingly enough, and it didn't work at all. I didn't think it had any interest, so I had to jump right into the main body of the story, and then tell the back story through flashbacks, which is the way I think the film should have been done, but nobody did films that way in those days."

"Here it is: money to burn!"

"[First lines] [Spoken over a shot of outer space] Needles in a heavenly haystack. There are more stars in the heavens than there are human beings on Earth. Through telescopes men of science constantly search the infinitesimal corners of our solar system seeking new discoveries, hoping to better understand the laws of the Universe. Observatories dedicated to the study of astronomy are set in high and remote places, but there is none more remote than Mt. Kenna Observatory in this part of South Africa."
