How long are they?
The fellowship DVD has about 30 minutes of extra fotage, and the Two Towers has about 40 minutes i think.
Plus both sets have two additional DVD's with doucumentaries that are about 3 hours long each, they are quit interesting.
The extended versions are unlike any other DVD I have seen. The scenes that were left out are full-fledged scenes (not just halfway done) and are seamlessly incorporated into the rest of the movie.
the reason why they go together so well is that they recut the movie after the cinema release. I mean they do everything recut the score, edit in the new clips it's like having an entirly new movie to produce in the time between the cinema realse and the special edition DVD's are realsed
