Dark Knight Blu-Ray First With BD-Live Features

The Dark Knight Blu-ray release is the first Blu-ray disc that supports special online features, otherwise known as BD-Live.
Blu-ray 2.0 player required. Hint: PS3 would be a good choice.
Launch the BD-Live feature on the disc and you’re prompted to create an account with Warner Brothers. The first part of the registration takes place on the disc, with the second portion requiring you to click a link that WB sends to your email.
The actual BD-Live features are available online via your computer. The main feature? User recorded commentary.
Warner Brothers allows you to stream the movie via the ‘net while recording your own video/audio commentary as it plays via webcam/mic. You can browse through the library of everyone else’s recorded commentary (kind of cool and random yet mainly pointless), in addition to a “Featured Commentary” list of hand-picked recordings by Warner Brothers. On the list: Paul Levitz, creator of DC Comics, and Jerry Robinson, the alleged creator of the Joker.
Other BD-Live features include some extra videos talking about the film’s soundtrack and a few animated comics. Nothing that couldn’t be found on a normal DVD. Oh, and you can send an ‘e-vite’ inviting your friends to watch the film “with” you on their own separate computers. Sweeeet.
User-recorded commentary is the only real offering here. Cool? Yeah. A little underwhelming? Yep. The only tracks anyone wants to hear are those by the pros. Put em on the DVD.
