Directors Commentaries and behind the scenes documents were (and still are to an extent) the main reason I buy physical Blu-Rays. Apple's store (not Apple TV, but the one you can "buy" movies from) has actual extras for a good selection, but they're still at the whim of one company to take away. Nothing will ever beat three things, the cast commentary on Tropic Thunder ("Man, I don't drop character 'till I done the DVD commentary." - and he doesn't), the commentary on Deep Blue Sea (Samuel Jackson f's off the studio when his character dies halfway) and the sheer insane volume of BTS material on the LOTR extended DVD boxes.
