I spent most of the afternoon watching THE SCORPION KING on Blu-ray. Since I had watched the movie again over the weekend, I immediately turned on the U-Control (picture-in-picture) feature, and, of course, I much prefer this way of doing commentaries for modern action movies as opposed to the voiceover type of commentary that seems more appropriate for more serious films.
In this, you get commentary from many peoduction personnel, behind the scenes footage, storyboards, but it's not constant. And the neat thing is that the movie was done in DTS-HD MA sound, but when the pop-up windows came on that had audio, the main channel sound would subside and the sound for the window would take over. Then, the full strength DTS-HD MA would come back when the pop-up was finished.
