Peter Jackson’s “The Fellowship of the Ring” was an extraordinary introduction to his “Lord of the Rings” trilogy. It not only introduced us to its compelling assortment of characters, but it also firmly planted us within J.R.R. Tolkien’s vast enchanting world. But it’s the second installment, “The Two Towers” where the series truly hits its stride.

“The Two Towers” takes the story of its predecessor and expands it in every way. Fascinating new characters, more lands throughout Middle-Earth, and even higher stakes than before. But one of Jackson’s many great accomplishments is how seamlessly he blends these new pieces into the existing fabric. And despite the immensity of his scope, the movie never loses its intimacy.

Picking up where “Fellowship” left off, Frodo (Elijah Wood) and Sam’s (Sean Astin) journey to destroy the One Ring has grown more arduous and the weight of the ring more burdensome. As the two struggle to find a path to Mordor, the sallow, emaciated Gollum (Andy Serkis) secretly follows them. He was the ring’s former owner, consumed by its power and desperate to reclaim it. When Gollum is discovered Frodo shows pity and uses him as a guide against the pleas of a concerned Sam.

A second story thread follows Aragorn (Viggo Mortensen), Legolas (Orlando Bloom), and Gimli (John Rhys-Davies) as they follow the trail of their abducted Hobbit companions Merry (Dominic Monaghan) and Pippin (Billy Boyd). They are led through the war-torn lands of Rohan whose King Theodin (Bernard Hill) lies under a spell of the wicked wizard Saruman (Christopher Lee).

And yet a third story thread follows the aforementioned Merry and Pippin who manage to escape their Uruk-hai captors after the Orc soldiers are attacked by Éomer (Karl Urban) and his exiled Riders of Rohan. The two Hobbits hide deep within Fanghorn Forest where they encounter a mysterious tree beings called Ents.

The challenges for this incredible three-headed story are obvious. Huge in scale and with a ton of ground to cover, yet vitally important that it all comes together. Jackson melds together his many moving parts with remarkable precision. And of the several new characters introduced not a one feels wasted or undeserved. Each fit and have a place in Tolkien’s tumultuous world yet have their own personal storylines that take form without ever feeling pointless or intrusive. It’s a remarkable mixture of character and narrative.

Then there is the genius of Jackson’s technique. From his sweeping camera combing the exquisite New Zealand landscapes to the subtlest of closeups capturing every worry, concern, and pain of the characters. Equally exhilarating are the action scenes both small and epic in size. It’s hard not to be blown away by his framing of the action as well as Weta Workshop’s extraordinary special effects. Jackson really opens it up with the first of the series’ huge battlefield sequences. The Battle for Helm’s Deep remains my favorite segment in the entire trilogy.

Much more could be talked about including Jackson’s knack for not only building tension but maintaining it throughout a sequence. Also “The Two Towers” highlights Jackson’s keen ability to convey to the audience an incredible sense of the mystical and magical. The world he and his teams place us in are rich with imagination and the fantastical. But the greatest thing about the series is that it’s far more than eye candy and sparkly window dressing. It’s the characters and their stories that form the heart of trilogy. That’s especially true for “The Two Towers”.
