28 Days Later (Widescreen Special Edition)
Even though it's only a single disc, the28 Days LaterDVD includes a lot of very interesting features, including the alternate ending that was shown after the end of the film a couple months into its theatrical run.  It's much bleaker, as director Danny Boyle and writer Alex Garland say in their optional commentary.  Another alternate ending is almost the same as the theatrical ending but slightly less happy.  Most interesting is the "radical" alternate ending that takes an entirely different path midway through the film.  It wasn't filmed, however, so Boyle and Garland narrate the action over storyboards, and it's a surprisingly engrossing 11 minutes.  Boyle and Garland also did a commentary track for the film, and they talk about how they were able to get the shots of deserted London and why they used the ending they did.  There are also six very watchable deleted scenes, and Boyle and Garland's comments range from "great sequence" to "a disgrace." Slightly less relevant is a 24-minute documentary that spends its first 10 minutes on the real-life threat of infectious diseases before recapping the film and discussing such elements as the use of digital video and the boot camp the actors had to attend. If you need any further proof that the DVD was a labor of love, even the stills galleries have commentaries.--David Horiuchi
