There are two versions of the DVD (not including the blu-ray edition); the standard DVD and a two disc special edition. While the special edition has a bevy of extras, the standard DVD has one extra: “Wolverine Unleashed: The Complete Origins” is a behind the scenes featurette which runs under 15 minutes. It covers why this story was chosen over the original story of Wolverine’s Samurai days in Japan which will be the plot of the sequel – studio interference as they said the full origin needs to get out of the way before tackling a new story. It also covers some of the special effects and has interviews with producers and star Hugh Jackman. The featurette is interesting, but for more extras including deleted scenes, an alternate memory erase sequence and interviews with Wolverine creator Len Wein and X-Men creator Stan Lee, you’ll want to pick up the special edition.
Hopefully now that the origin story has been told, we’ll have the “Wolverine in Japan” story, there are several storylines that can be adapted, but the best would be the 1982 Wolverine mini-series by Chris Claremont and Frank Miller. Only time will tell what the inspiration for Wolverine 2 will be.
