I went of a movie frenzy last week and got to watch all 3 of the LOTR movies, the extended version. I know right? I am that obsessed ;P although my Twin Towers CD did not work, and I am disappointed. And I did not watch the whole 12 hours straight, that would be crazy. :P I will always love this trilogy, now I wish I could've wait a while longer and gotten them in DVDs instead. *sigh*
I would have to say my favorite is The Two Towers. It has the funny fight scenes between Legolas and Gimli. Which movie is your favorite?
