What do you get?
Both the theatrical and extended versions of The Return of the King are on one double-sided disc. The versions use seamless branching, meaning that the scenes that are common to both versions are stored on the disc only once. If you choose to watch the extended version, the disc "branches" out to the added or extended scenes. What does this mean to the viewer? Not much. The viewing experience is the same because the branching is imperceptible. But because both versions of the film don't have to be stored on the disc in their entirety (which would be seven and half hours total), both versions together fit on two sides of one disc. The downside is that whichever version you watch, you have to flip over the disc halfway through; the film breaks at the same spot it did on the Extended Edition, right after the entrance of the wolf-head battering ram. Also lost are the meager features included on the theatrical edition, plus the four commentary tracks, two discs of bonus features, and DTS 6.1 ES sound from the four-disc Extended Edition.

What's new?
The second disc has an 112-minute documentary directed by Costa Botes, who was personally selected by Peter Jackson. Rather than the formal documentary structure of other editions, it consists of off-the-cuff interviews and random bits of behind-the-scenes action and special-effects work: The charge of the Rohan, the horses, the Mumakils, the lava of Mount Doom, and the burning of the ring. You'll also see Ian McKellen flubbing his lines and conducting the crowning ceremony in a flowery wig. It's entertaining, but because there's no structure (there are chapters, but no menu or chapter listing), it's not as convenient to watch, and go back to, as a documentary broken up into bite-size pieces. Note: New Line Home Entertainment couldn't release this material on its own à la the King Kong Production Diaries due to contractual restrictions.

Bottom line: Do I need this edition?
This Limited Edition combination of theatrical and extended versions plus new documentary seems likely to appeal to two camps. One is the devoted fan, who already owns both editions but has to have everything LOTR. The other is the casual fan who liked the movie in theaters, heard good things about the Extended Edition, and doesn't need a ton of bonus material. This edition is attractively priced for that buyer, and the packaging is quite handsome. In between is the devoted fan who already owns both editions but doesn't feel the need to watch more bonus material. When watching the whole movie, that fan will always choose the Extended Edition, but keeps the theatrical edition for (1) watching with guests, (2) the music video, or (3) the convenience of skimming through favorite scenes without having to change discs. That fan can safely skip this edition, as can home-theater fans who love DTS. --David Horiuchi
