The commentary was quite enjoyable to watch, too. I love in-depth behind-the-scenes stuff like that, when it comes to films I like, and I only wish they had delved even deeper.
I'm due to rewatch 'em. The Fellowship came out ten years ago this winter. But my discs are in storage in Seattle like most everything else I own!
I can't remember my very favorite moment, but I do recall how touching the climax was, where Sam and Frodo have done their duty and are on the slopes of Mount Doom waiting to die together. The ending song, "Into the West," was perhaps even more touching. Naturally, the artist who sang it is a left-hander. =D
