The second DVD that will come out for The Two Towers will have extra scenes that bring it to over 3.5 hours of running time.
The movie cut version of The Two Towers will be released in DVD on my birthday (August 26), but I’m holding out for the extended edition–it will be released in November. It looks like they have some pretty cool extended scenes. They even promise to explain why they trashed the character of Faramir so awfully (in my opinion, anyway–he was a much more noble and wise character in the book).
