The Princess Bride (1987)

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.

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!

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.

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?
