Other than Keanu Reeves, star of The Matrix and Bill & Ted movies (the Bill & Ted flicks are far better as a series), the HD DVD release of Constantine that we mentioned earlier will also be the first to feature bonus content exclusive to the HD DVD version. Using what they are calling In-movie Experience (IME), you can watch an interview with the director while the film is still playing.
This seems to be the first disc to use any iHD features, it will be interesting to see how well received this is by buyers, not to mention what sort of special features Blu-ray discs will launch with. Until now HD DVD has only offered SD extras copied direct from their DVD cousins, hopefully this marks the end of that era.
Update: VideoBusiness has more information on Universal's release of The Bourne Supremacy, which contains similar interactive features and should be on store shelves near you for $34.98. Batman Begins, Charlie and the Chocolate Factory (thanks WiFiSpy) and Dukes of Hazzard are also slated to get the interactive treatment, no release dates yet.
