The Lord of the Rings: The Fellowship of the Ring (2001)

Other mistake: When the hobbits are hiding under the tree trunk from the Ringwraith in the beginning, you can see space to the left and right of the tree above them. Logically when the Ringwraith walks past the tree you would see it on the right side of the tree first, then on the left, but you don't - it looks like it walks out of the tree instead of behind it. [Confirmed on the commentaries - Elijah Wood asks his fellow actors if anyone spotted the mistake: 'It kind of magically comes out of the tree'. Sean Astin: 'You mean it doesn't pass from the other side?' Wood: 'No, it comes out from the centre.'] (00:51:40)

Aragorn: Gentlemen! We do not stop 'til nightfall.
Pippin: But what about breakfast?
Aragorn: You've already had it.
Pippin: We've had one, yes. But what about second breakfast?
[Aragorn stares at him, then walks off.]
Merry: Don't think he knows about second breakfast, Pip.
Pippin: What about elevenses? Luncheon? Afternoon tea? Dinner? Supper? He knows about them, doesn't he?
Merry: I wouldn't count on it.

Trivia: According to the Guinness Book of Records, the Lord of the Rings holds the record for the greatest number of false feet used in one movie: 60,000.

Question: In the scene where Gandalf and Saruman are fighting in the tower Saruman takes Gandalf's staff and sends him to the top of the tower. What happened to Gandalf's staff? When he escapes he somehow gets his staff back and uses it the rest of the movie. Is it another similar staff, or am I missing something?
