<P> Another change is the fact Treebeard does not immediately decide to go to war . This adds to the tension, and Boyens describes it as making Merry and Pippin "more than luggage". Here, the Hobbits show Treebeard what Saruman has done to the forest, prompting his decision to act . Another structural change is that the Hobbits meet Gandalf the White early on, explaining why the Hobbits do not react to his return when they meet him again following Isengard's destruction . This was explained in the book by Gandalf arriving at Isengard in the middle of the night to talk to Treebeard . </P> <P> The filmmakers' decision to leave Shelob for the third film meant that Faramir had to become an obstacle for Frodo and Sam . In the book, Faramir (like Aragorn) quickly recognises the Ring as a danger and a temptation, and does not hesitate long before letting Frodo and Sam go . In the film, Faramir first decides that the Ring shall go to Gondor and his father Denethor, as a way to prove his worth . In the film, Faramir takes Frodo, Sam and the Ring to the Battle of Osgiliath--they do not go there in the book . Jackson winks to readers with Sam's line, "By all rights we shouldn't even be here, but we are ." After seeing how strongly the Ring affects Frodo during the Nazgûl attack, Faramir changes his mind and lets them go . These changes reshape the book's contrast between Faramir and Boromir, who in The Fellowship of the Ring attempted to take the Ring for himself . On the other hand, (which can be seen only in the film's extended version), it is actually their father who wants the Ring and urges Boromir to get it, while Faramir only wants to prove himself to his father . Boyens contends these plot changes were needed to keep the Ring menacing . Wenham commented on the DVD documentaries that he had not read the book prior to reading the script, so the film's version of Faramir was the Faramir he knew . When he later read the book and noticed the major difference, he approached the writers about it, and they explained to him that if he did say "I wouldn't pick that thing up even if it lay by the wayside", it would basically strip the One Ring of all corruptive power . </P> <P> The meaning of the title itself,' The Two Towers', was changed . While Tolkien considered several possible sets of towers he eventually created a final cover illustration and wrote a note included at the end of The Fellowship of the Ring which identified them as Minas Morgul and Orthanc. Jackson's film names them as Orthanc and Barad - dûr, symbolic of an evil alliance out to destroy Men that forms the film's plot point . The film depicted Saruman openly presenting himself outright as Sauron's servant, whereas this association was not explicitly stated in the novel (and indeed analysis by Gandalf and Aragorn in the chapter "The White Rider" stated that there was a rivalry instead, as Saruman was afraid of the prospect of being at war with Sauron, if Rohan and Gondor fell). </P> <P> When Alan Lee joined the project in late 1997, Helm's Deep was the first structure he was tasked to design . At 1: 35 scale, it was one of the first miniatures built, and part of the 45 minute video that sold the project to New Line . It was primarily drawn from an illustration Lee had once done for the book, though fellow illustrator and designer John Howe suggested a curved wall . Used in the film for longshots, Jackson also used this miniature to plan the battle with 40,000 toy soldiers . </P>
