Picking up where the first film left off, Peter Jackson's THE TWO TOWERS throws the remaining members of the Fellowship into the scattered chaos of Middle-earth, now fully under siege by the forces of Sauron. While Frodo (Elijah Wood) and Sam (Sean Astin) journey to the dreaded Mordor, Merry (Dominic Monaghan) and Pippin (Billy Boyd) are held captive by orcs, and Aragorn (Viggo Mortensen), Legolas (Orlando Bloom), and Gimli (John Rhys-Davies) search for their abducted companions. Soon Frodo and Sam are joined by the sulking and duplicitous Gollum (portrayed by the voice and motion-captured acting of Andy Serkis), who becomes their guide through the barren lands leading to Mount Doom. Meanwhile Merry and Pippin encounter the looming Treebeard (voiced by Rhys-Davies) and Aragorn, Legolas, and Gimli find themselves in the land of Rohan, accompanied by an old friend. As the tale continues, each scenario becomes more perilous, and fierce battles erupt at both Isengard, home of the treacherous Saruman (Christopher Lee), and the massive Helm's Deep.
