- Cara Carozza, the dancer: You gamble with money, with people and with fate and most horrifying of all, with your own self.
- Countess Dusy Told: I have learned of something that until recently I didn't believe, that there still apparently exists in this world something more valuable and more deeply moving than the strongest thrill. Love , , ,
- Dr. Mabuse: There is no love. There is only desire! There is no happiness. There is only the will to power!
- Countess Dusy Told: I'm afraid there's absolutely nothing in this world that can hold my interest in the long run. Everything that can be observed from a car, from a theater box or from the window, is part repulsive, part uninteresting, and, at least, boring.
- Dr. Mabuse: You're right, Countess. Nothing in this world is interesting in the long run, except for one thing: Gambling with people and with the fates of people.
- Prosecutor von Wenk: [On the phone] This is Prosecutor von Wenk! Dr. Mabuse, I ask you to offer no resistance against the state authorities and turn yourself in.
- Dr. Mabuse: I feel like a state within a state with which I have always been at war! If you want me, come and get me!
- Prosecutor von Wenk: We are prepared to move against you using the harshest measures. Give up your senseless resistance!
- Edgar Hull: I played and I lost. But to whom exactly?
- 17 + 4 Club Member: To your friend!
- Edgar Hull: Friend? What do you mean? It's the first time I've seen the man. Who brought him into the club?
- 17 + 4 Club Member: I think you've had too much to drink, Hull! First, with your bad luck you call "go bank" and then you claim not to know the very man that you yourself invited into the club!
- Prosecutor von Wenk: What's a woman like yourself doing in such a place, amongst pushers, gamblers and call girls?
- Gräfin Dusy Told: We have weary hearts, Mr. von Wenk. We need thrills of a very special nature in order to endure this life.
- Prosecutor von Wenk: This man, the enemy I pursue, I do not know who he is. I only know that he exists.
- Prosecutor von Wenk: [Password] Pineapple.
- Waiter, Club Andalusia Palace: Cocaine or cards?
- Prosecutor von Wenk: Cards.
- Dr. Mabuse: About to make a fuss, you swine? What am I paying you for, if at the first opportunity you flounder like schoolgirls?
- Cara Carozza, the dancer: You do seem to possess the "open sesame" to every secret door, Mr. Prosecutor.
- Dr. Mabuse: Now the world shall learn who I am! I, Mabuse! I will become a giant, a titan who scatters the gods and the laws into a swirl like withered leaves!
- Prosecutor von Wenk: The man for whose sake you are being held has tossed you out like fruit that's been squeezed dry.
- Georg, the Chauffeur: We can't go out. The police have the house surrounded!
- Dr. Mabuse: Then it's war!
- Edgar Hull: [after a night of cards playing "Mr. Balling"- the mind-controlling Dr. Mabuse in disguise] I've lost again. Until tomorrow afternoon, you'll have to make do with 20,000 marks and a promissory note of 150,000 marks.
- Title Card: If you can't find your man, you just might find your woman!
- Prosecutor von Wenk: For approximately six weeks, complaints of predatory gamblers have been coming into the authorities. It's been impossible to prove foul play in any of these cases. However, their luck in the game is so improbable, that something surely is amiss. It's always someone different. Sometimes it's a young gentleman, at other times a respectable shopkeeper. Today it's a blond American, tomorrow a dark-haired Russian. It is always someone different.
- Countess Dusy Told: I prefer to observe the passions that gambling arouses, reflected in the mirror of others, without coming into close contact with such players themselves.
- Countess Dusy Told: I need in life a strong breath of extraordinary thrills and adventures; but, I fear such things have become extinct.
- Dealer, Petit Casino: Ladies and Gentlemen, it is an honor and a distinct pleasure to officially inaugurate the Petit Casino in your esteemed presence. The Petit Casino has taken it upon itself to satisfy in every respect even the most extravagant of your wishes. Surrounded by the most modern of settings and appointments, you will feel yourself transported back into the golden age, when there was only one motto: "All that pleases is allowed."
- Dealer, Petit Casino: Let the games begin!
- Dr. Mabuse: I'll give you one more week for Wenk, so you can get the job done right, but not one minute longer.
- Cara Carozza, the dancer: The prosecutor is finally at the end of his rope. And now he hopes to get help from me. From me, a woman who's just as wretched and forsaken as a stray dog.
- Cara Carozza, the dancer: Nobody knows who he really is. He exist! He lives! He towers over the city. He is damnation and heavenly bliss. He is the greatest man alive. And he loved me.
- Dr. Mabuse: [Posing as Sandor Weltmann] Ladies and Gentlemen, I would now like to demonstrate for you one of the most typical cases of mass suggestion, which is not unlike the tricks of the Indian Fakirs which arise from it.
- Title Card: Philharmonic Hall - Scientific Presentation Series - Today: Lecture by Dr. Mabuse, Professor of Psychoanalysis - "Psychoanalysis as a Factor in Modern Medicine" - Lecture begins at 8:00. Guests welcome. The Union of Psychoanalytic Research.
