The Princess Bride (1987)

Visible crew/equipment: After Wesley sets the ROUS on fire, as the ROUS is writhing on the ground, you can see a crew member (fire safety?) walk into view beneath one of the roots of the trees on the right-hand side. (00:47:35)

Continuity mistake: After Montoya has hauled Wesley to the top of the cliff, he drops the rope on the ground, where it lands forming a couple of coils. You can see this as Wesley sits down and Montoya leans up against the wall. However, when they start their duel, the rope is hanging straight off the cliff, without any coils in it.

Twotall

Revealing mistake: When Inigo and Westley are duelling, they are making athletic jumps. One does it after the other and when they land you can see the mat wrinkle under the "dirt" on the ground.

Trivia: Mark Knopfler, who composed the music to the Princess Bride, only agreed to do so if Rob Reiner could include the baseball cap he wore in the film Spinal Tap. The director placed the cap in the boy's bedroom, beside the bed.

Trivia: In the scene where the R.O.U.S. is snuffling around, it's the director, Rob Reiner, who is making the snuffling noises.

Trivia: When Count Rugen knocks Westley out to put him in the Pit of Despair, Cary Elwes wanted the scene done properly, so he told Chris Guest to hit him for real with the sword butt. Guest did, and accidentally hit him hard enough that production had to be shut down for a day while Elwes was taken to the hospital.

Inigo Montoya: That Vizzini, he can fuss.
Fezzik: ...fuss...fuss... I think he likes to scream at us.
Inigo Montoya: Probably he means no harm.
Fezzik: He's really very short on charm.
Inigo Montoya: Oh, you've a great gift for rhyme.
Fezzik: Yes, yes, some of the time.
Vizzini: Enough of that.
Inigo Montoya: Fezzik, are there rocks ahead?
Fezzik: If there are, we'll all be dead.
Vizzini: No more rhymes now, I mean it.
Fezzik: Anybody want a peanut?
Vizzini: AARRGGHH!

Vizzini: Inconceivable!
Inigo Montoya: You keep using that word. I do not think it means what you think it means.

Inigo Montoya: Who are you?
Westley: No one of consequence.
Inigo Montoya: I must know.
Westley: Get used to disappointment.
Inigo Montoya: Okay.

Question: When Buttercup confronts a masked Westley, she says that she loved more deeply than a killer like him ever dreamed. Westley's response is to raise a hand as if to hit her, but he stops and says that was a warning and that where he comes from, there are penalties when a woman lies. In what way was Buttercup lying?

Question: Inigo shows Westley the sword his father made for the 6-fingered man ("I've never seen its equal"). How did Inigo acquire this sword? You would think that if Count Rugen was prepared to kill Domingo for the sword then he would have taken it with him.

Question: What does Miracle Max mumble before agreeing to help Inigo and Fezzik with mostly-dead Westley? It's after Inigo says "humiliations galore," as Max is turning away to get his hat.
