in Europe the Trilogy box is also the only DVD item you can buy. The extra scenes, my friend, makes you wish they never stopped the movie(s) after 3 hours. With them in it (I believe the US tv saga version was with those scenes included) the story is not just longer but even better. It has some more scenes from the novel (like some Woltz scenes). And it has a nine hour long audio commentary, off course, if you can sit it through.

And I think you'd even like the Behind-The-Scenes extra's, I certainly did (learn about how an entire Little Italy street was in 1974 transformed to a 1917 setting, it's enormous!)
