I just throught I would start a discussion thread pertain to some of the great PiP commentary tracks that HDDVD (and hopefully soon Bluray) are offering. As most of us know, '300' comes out on 31/07/2007 and will feature PiP commentary track that is supposed to be excellent. I for one am thuroughly look forward to this feature and hope that it is as good as many of the early reviews are making it our to be. But 300 is not the only film to have a great PiP commentary track. I have just finished watching The Bourne Supremacy PiP commentary and it is extremely entertaining and informative. The thing I like more about it is it is very screen specific. It is basically a montage of cuts and extended cuts from some of the featurettes all pieced together and very well edited. It runs the complete length of the film and there literally is not one second of dead air. It even features little countdowns to certain more signifacant parts of the film and is is a little more comprehensive for these parts. I could not recommend this commentary enough. Another great PiP commentary track is M I 3. This is more your traditional commentary which has the director and Tom Cruise sitting together and watching the film and going over their experiences and how they made the scene. The unique part in this track is that there are times where the director will ask to have the film stopped and then will play he will swithc the main screen to a blooper or deleted section, and then will have them both play simutaneously so that you can see the difference. Batman Begins also has a great commentary track very similar to the Bourne Supremacy, but not nearly as polished. What other PiP commentary tracks have you found enjoyable?
