I've noticed a recent trend where a movie will come out in two different versions on the same day-a single disc movie only version, and a multi-disc SE. Recent examples include Charlie and the Chocolate Factory, Batman Begins, and Fantastic Four. While I'm glad that the studios are giving people the SE right away, I have to wonder why they're even bothering with the stripped down version in the first place. Looking at Batman Begins, the SE was the same price as the single on release day, and even the list was only a couple bucks higher. I'd think that if you're paying to press the extra disc and produce the features anyway, why not just release the movie in one SKU? Retailers will only have to carry one version of the movie, and anyone that doesn't want the second disc of extras just won't watch it. Wouldn't the costs balance out? I can only really think of a couple of reasons that this would happen, and I think it's got something to do with Blockbuster. First, having a single disc release means that when BB buys 100 copies of Batman Begins for rental, they only have to keep track of 100 discs (instead of 200). Second, I know there's a lot of people like me who buy most of their new release DVDs used from Blockbuster, since you're essentially getting exactly the same product for as little as 1/3 of the price. If I wanted any of the Batman Begins extras though, I'd have to buy the disc brand new, since Blockbuster only carried the single disc release. Since the studios don't make anything on used DVD sales, perhaps this is a move to try to convince people to buy more new discs (instead of waiting to get it for 6 bucks two or three months after it's released). Can anyone think of another reason to produce two different versions of a movie at the same time for close to the same price?
