"Did you know, Putnam, more people are murdered at ninety-two degrees Fahrenheit than any other temperature? I read an article once - lower temperatures, people are easy-going. Over ninety two, it's too hot to move. But just ninety-two, people get irritable."

"We are right, and we're not crazy. And if we've been seeing things, it's because we did see them."

"[the cat appears] It's only Neutron. We call him that because he's so positive."

"[to reporters] You boys like to call this the pushbutton age. It isn't, not yet. Not until we can team up atomic energy with electronics. Then we'll have the horses as well as the cart."

"If she looked upon the horror her husband had become... she would scream for the rest of her life!"

"She had to kill the thing her husband had become—but could she?"

"The monster created by atoms gone wild."

"Help! Help me! Please help me! Help me!"

"You've committed murder just as much as Helene did. You killed a fly with a human head. She killed a human with a fly head."

"No, Helene and Andre believed in the sacredness of life. They wouldn't harm anything... not even a fly."

"The search for the truth is the most important work in the whole world — and the most dangerous."

"The more I know, the more sure I am I know so little. The eternal paradox."

"God gives us intelligence to uncover the wonders of nature. Without the gift, nothing is possible."

"I can transport matter — anything — at the speed of light, perfectly. Of course this is only a crude beginning, but I've stumbled on the most important discovery since man sawed off the end of a tree trunk and found the wheel. The disintegrator-integrator will change life as we know it. Think what it means. Anything, even humans, will go through one of these devices. No need for cars or railways or airplanes, even spaceships. We'll set up matter-receiving stations throughout the world, and later the universe. There'll never be famine. Surpluses can be sent instantaneously at almost no cost, anywhere. Humanity need never want or fear again. I'm a very fortunate man, Hélène."

"I had just read 'The Silent World' by Jacques Cousteau and found it to be new and exciting. So when that picture came along, I wrote all the underwater stuff and went to Roger and told him I’d direct all the underwater parts for $100. He said 'okay.' If I had just asked, he would have said 'no.' I had to put it in a way that he would jump at. So I directed all that stuff and it was rather funny. I’d be down at the bottom of the tank at Marineland trying to get actors to do something while (director of photography) Floyd Crosby was hammering at the glass window trying to get them to do something else. It was all pretty silly."

"Roger came to me and said, 'I want to make a picture called 'Attack of the Giant Crabs,' and I asked, 'Does it have to be atomic radiation?' He responded, 'Yes.' He said it was an experiment. 'I want suspense or action in every scene. No kind of scene without suspense or action.' His trick was saying it was an experiment, which it wasn't. He just didn't want to bother cutting out the other scenes, which he would do."

"In archaeology all things are possible."

"Archaeologists are underpaid publicity agents for deceased royalty."
