- Charles Matin: There'a a certain amusing irony in offering a man's own money for his capture. Fifty thousand francs? Why not?
- Lorraine Lavond: [referring to the disguised Lavond] Toto, I have the strongest feeling I've seen him somewhere before.
- Toto: You have.
- Paul Lavond: [with emotion to Lorraine about her "father", clearing his throat mid-sentence] Then he said that was the most important thing of all. He told me to tell you to forget him, to find happiness and keep it, to marry and give your children all the love you might have given him if he hadn't been taken from you.
- Paul Lavond: [a policeman has just left the shop, failing to recognize Lavond in disguise as Mme. Mandilip] Stupid policeman... To let an old white wig cost him one hundred thousand francs.
- Malita: It might have been safer to take him downstairs and make him "small."
- Paul Lavond: He's small already, in mind. In fact, Malita, if most men were reduced to the dimensions of their mentality, Marcel's plan wouldn't be necessary.
- Paul Lavond: I may not look it, madame, but I was once a very successful banker. Three men - my partners - lied and tricked me into prison. Well, three lives are going to pay for it.
- Paul Lavond: Look at me and see what seventeen years in the grave has done to me. No, Radin, without my hatred I never could have lived to exhume myself. What swine you three are!
- Marcel: [as he and Lavond are on the run having escaped from prison] I have work to do. I've dreamt only of my work.
- Paul Lavond: Well, my work is no "dream" - I've been awake for seventeen years!
- Marcel: But you have only hatred in your heart. My work will help the world to live!
- Paul Lavond: And my work will help three men die.
- Marcel: [explaining why he thinks shrinking people and animals is a good idea] Lavond, my friend, millions of years ago the creatures that roamed this world were gigantic. As they multiplied, the earth could no longer produce enough food. Think of it, Lavond: every living creature reduced to one-sixth its size. One-sixth of its physical need. Food for six times all of us!
- Malita: [after Lachna has been shrunk] You've corrected her brain, Marcel. She's no longer the stupid half-wit. Oh, she's going to be beautiful!
- Paul Lavond: [after having observed the shrinking of Lachna] This is like some horrible dream. I don't want any part of this! Restore her to what she was!
- Malita: No, she will always remain small. Small! We can make the whole *world* small, as Marcel wanted. We can go to Paris. There are many people there... there's where we begin our work!
- Paul Lavond: Yes, Malita.
- Laundry Proprietress: Huh! It's amazing how you washed-out Cinderellas can speed up work when five o'clock comes around.
- Malita: This is wonderful, Lavond. Now that you are free, we can go on with our work, without being bothered by the police.
- Paul Lavond: No, Malita, my work is over, but I am not free. Why, if they ever found out who I was, the police would want a lot of questions answered: What happened to Radin? Who paralyzed Coulvet? No, Malita, when I proved my innocence, I condemned myself forever.
- [last lines]
- Eiffel Tower Elevator Operator: [riding down the Eiffel Tower elevator] It's a nice evening, monsieur.
- Paul Lavond: Yes... Probably the nicest evening of my life.
- Paul Lavond: [as Mme. Mandilip, examining Mme. Coulvet's expensive necklace up close] Forgive me, madame, but I do love the beautiful. You can tell that from my workmanship.
