There are just too many epic scenes to pick from this trilogy! One such scene was the awesome scene with Gandalf the Grey and the Balrog. When the Fellowship was fleeing the Mines of Moria, they were unfortunate enough to encounter a nasty Balrog, who was intent on having someone. Gandalf stood against the Balrog in an attempt to get the Fellowship out safely, and while he was doing so delivered some pretty cool lines.
