Continuity: When Westley and Inigo are duelling at the Cliffs of Insanity, Inigo makes a strong gesture (feet together, right arm holding sword extended downward, left arm up extended backward). When the camera angle changes, the duel picks up a couple of seconds before that stance and he does it again.

Audio problem: In the scene where Fezzik is putting Inigo's head in a bucket of water, every time he dumps Inigo's head in the water, you hear his deep breath. Not when his head is pulled out of the water.

Continuity: Watch the red car behind Fred Savage in the bedroom. In close shots, the car is pointing towards the camera. In wide shots it's pointing sideways.

Revealing: When Fezzik puts the "almost dead" Westley down on the castle wall where they look out to the gate door, the wall moves. In fact, inside the castle when Fezzik breaks down the door for Inigo, the wall moves then too.

Continuity: After Westley is injured in the Fire Swamp, the wound on his shoulder changes colour and position for the rest of the movie.

Continuity: When Buttercup jumps down the window, she is falling in a vertical position but in the next shot, just before she falls in Fezzik's arms, she is suddenly in a horizontal position. Submitted by Sereenie
