The Two Towers: Differences Between the Book and the Movie

Now, the differences between the book of The Fellowship of the Ring and the movie of it were more extensive then previously thought, but still pretty good for a film adaptation. The Two Towers is where things get nasty, consistency-wise.
One difference that isn't quite as important is that you didn't know about the whole orc attack and the death of Boromir at the end of the first book, but the first movie ended after Boromir's body is released on the River Anduin. Honestly, the first movie had a better ending than the first book did. Boromir's death was a WAY better place to let off then Frodo and Sam leaving just before that.
The film version of The Two Towers actually didn't have many inconsistencies for the first few minutes, at least not until they left for Helm's Deep. That's where the differences get nasty. Remember in the movie how everyone just packed up and left Edoras? In the book, Theoden left Eowyn in charge with a small company of Riders to protect those that stayed behind.  But that still isn't too bad. There's one huge difference in the sequence leading up to Helm's Deep that threw off the end of this movie and the first half of The Return of the King. And that was when Aragorn and his horse were dragged off the cliff by the Warg. That didn't happen in the book. They weren't even attacked on the way to Helm's Deep. If Peter Jackson had gone along with the book, he would have been able to end the second movie with Shelob's Lair like the book did. But at the same time, the sequence where Aragorn is dragged off the cliff and the dreams that follow create a lot of tension, both in fear for Aragorn's life and romantically. See, Tolkien's problem was that there wasn't any actual romance present in the Trilogy. Arwen just kind of popped in the third book and they got married. But this whole issue with Elrond wanting her to cross the sea and her being torn between Valinor and Aragorn creates a lot of tension that makes the movie a lot more exciting.
Remember the elves that come right before the Battle of Helm's Deep to help? In the book, the Rangers/Dunedain showed up. That's something I wished would have happened in the movie, because their coming to help shows the reader that Aragorn's kinsman care about each other, and they are in fact there to help people like they say.
Other than those three things, the differences are very small. The Fellowship scenes and the Sam/Frodo scenes are integrated instead of being separate like they were in the book, but that's an improvement. The differences in the Return of the King are honestly almost as great as the ones in this, especially when it comes to the ending. You'll see when I write the post for the differences between the book and film versions of The Return of the King.
