Avatar: Director audio/video tracks to run concurrently with Blu-ray DVD
James Cameron has three High Definition camera crews following him around while shooting "Avatar". More specifically, these crews are using technology to outfit a new feature of Blu-ray players that will allow the simultaneous viewing of the main movie AND the director speaking in another box. You may switch from one to the other as being in the foreground and the same applies to the audio. Sweet feature.
There will most likely be a trivia game and/or some simple videogames included on the Avatar Blu-ray DVD when it becomes available. Another thing to keep in mind is that Cameron is a gaming aficionado and may very well want to include a Sony PS3 game in with the DVD set. :-)
Avatar is worth waiting for and Cameron is making sure it is worth owning too.
