We know you're hungry for every last morsel of information on Warner's hotly-anticipated Ultimate Matrix Collection on Blu-ray, so here goes. Warner Home Video just released information confirming that the data we already had was true, and that a seven-disc BD box set would be landing on (and shortly departing from) store shelves on October 14th. Aside from housing the complete trilogy with lossless 5.1 Dolby TrueHD audio, the package will also include an hour of special features on each film. More specifically, you'll see the studio's In-Movie Experience alongside The Animatrix (which is debuting in high-definition here), 35 more hours of undisclosed bonus material and a digital copy of The Matrix. Yeah, $129.95 is still the asking price, but you know it'll be going for a bit less on launch day.

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.
