Shelob's Lair

[dancing spawn of ungoliant]

How come in the books Shelob is at the end of the second one , yet in the movie its in the third?

1. They decided that they can't have two so opposite climaxes so close to each other. First there's the great victory of Helm's deep and then after a while there would be a hideous giant-spider. It would ruin the feeling of the Helm's deep.

2. In the book the journeys of Frodo & Sam and the rest of the Fellowship are written separately. Since PJ decided to mix them, he had to consider the dates, what happened, when and to whom. In that case, Shelob and Helm's deep doesn't match by timing -> Shelob belongs to the 3rd film.

Shelob ate orcs whenever she got a chance. It is mentioned in the book. Remember the orc that Shelob forgot hanging upside down in her lair...poor orc.
