When the guards are struggling with Horth in the hallway, notice the guard on the left as they turn him around. His machine gun is over his shoulder and it bends as it presses against the wall, revealing it to be made of rubber.
While Solo, Kuryakin, Raven, and Horth are spying on a camp from rocks high above, Horth stands up, ready to go, and catches Solo under the chin with his rifle.
Solo: (looking at photos to prepare for the mission) Let's look at the, uh, owner of the yacht. (seeing Gervaise Ravel) Mmm-hmm... very handsome owner.
Heather: If you like the feline type.
Solo: Well, they purr so nicely.
Heather: She's classified as dangerous.
Napoleon: A beautiful woman should always be so classified.
Heather: Me, too, Mr. Solo?
Napoleon: Oh, top of the list, Ms. McNabb.
Marion: Would you like some coffee? Shall I play a record?
Illya: You probably don't have anything I like. Just forget I'm here.
Marion: That won't be easy. (Illya sits in a chair)
Illya: Just... part of the furniture.
Marion: It seems whenever we're together you always have a gun in your hand. I'm never quite feel comfortable with you here.
Illya: You have to learn to ignore. Pretend I'm part of the background. Just another rock or a tree.
Marion: All right. You're a rock. (she leans against him)
Marion: Illya! Why...?
Illya: Please, I must think. There has to be some way out of this.
Marion: There isn't, so can't we just talk?!
Illya: No, just pretend I'm not here. Part of the walls.
Marion: That's what you are, all right. Pretend you're part of the walls or a lamp or a chair or a tree or a rock. But just for once, just once, couldn't you pretend to be a human being?
Illya: For a few moments then. Just pretend I'm a human being.
Marion Raven: Someone once said there can be no mischief where there's music. Do you believe that?
Marion is trying to diffuse the tense situation in her apartment by referencing a quote from a famous Spanish author, Miguel de Cervantes (1547-1616). In the 1615 novel Don Quixote, Part II, the character Sancho says to a duchess: "Senora, where there's music there can't be mischief."
