Corrected entry: When Merry and Pippin run in on the Secret Council, you can see Elrond watch them come past him. However, for a few frames you can see that he keeps looking at where they came from even when they have gone past him. This is probably because they were superimposed on to the film.
Corrected entry: When Bilbo drops the Ring on the floor of Bag End and it thuds, a magnetic floor was used so the Ring wouldn't bounce.
Corrected entry: You can see the Black Rider's effects mask when he's asking the hobbit about "Shire. Baggins". There's a bluish glint on it.
Corrected entry: In the scene where Pippin asks "Well what about second breakfast?" Merry and Pippin are thrown a piece of fruit each. Pippin is thrown his on the right side of his body, yet it ends up in his left hand. The fruit is also red in colour whilst being thrown, but orange in his hand. (00:56:05)
Corrected entry: Peter Jackson's son Billy (seen listening to Bilbo's troll story) is the only hobbit in the movie that didn't need a wig.
Corrected entry: It is rather interesting that the German dubbed version of FOTR follows Tolkien's guidelines for pronunciation more closely than the original English version. In the Appendices to the novel (Appendix F, 'On Translation') Tolkien states that Sam's name is not of Hebraic origin but short for 'Samwise' (an Anglo-Saxon word, Tolkien being a lecturer in Anglo-Saxon and Old English) and therefore not to be pronounced similarly to the abbreviation for 'Samuel'. Instead the name would have been pronounced [sahm] (the 'a' like in British English 'fast'). Another example is with place names such as 'Isengard' ('Isen' rhyming with 'treason').
Corrected entry: Just before the scene in which Pippin complains about not having "second breakfast", the shot changes to show an overview of the forest they're in. Before the scene changes, look in the top right hand corner of the screen. The trees there appear to be forming a circle with a hole in the middle. Slow motion or pausing isn't necessary, but it makes it easier to spot.
Corrected entry: This happens when Sam and Frodo are in Farmer Maggot's cornfield, just before they encounter Merry and Pippin. Sam emerges on to the path and can't see Frodo, so he runs down the path, calling out for him. As he does so, a rhythmic squeaking noise is audible, which is heard at no other time when he runs. This would appear to be the camera trolley moving along the track, either filming him running or moving to simulate his point of view.
Corrected entry: When they're on the road and you see Frodo, there are barely any leaves around his feet. It cuts to the shortening road, then back, and Frodo's feet are surrounded by leaves. And when they're on the road, the hill they drop off is steep and green. When they hide, the verge is no longer grass-covered and is more level.
Corrected entry: In the deleted scene where the Fellowship looks down into the mines in Moria, you can see a moving crew member with a torch down on one of the ledges.
Corrected entry: In the scene at the Council of Elrond, right after Frodo says, "I will take it," there is a shot of all the members of the council staring at Frodo. The problem is, they are not all staring in the same spot. (Look closely at Boromir and Gandalf, they look as though they could be staring at Frodo. But the two elves on the right of the screen are staring too far off to the right.)
Corrected entry: The books were published in the mid-1950s as three different stories, much to the annoyance of author J.R.R. Tolkien, who had never intended the work to become a trilogy.
