iTunes 11.3 includes all-new iTunes Extras for HD movies. iTunes Extras can include behind-the-scenes videos, short films, high-resolution image galleries, director's commentary, scenes, and more. These immersive iTunes Extras can also be enjoyed on Apple TV with Software Update 6.2 now, and will be available on iOS 8 this fall.
New iTunes Extras will be automatically added to your previously purchased HD movies as they become available - at no additional charge.
iTunes 11.3 can be downloaded from the software update tool in the Mac App Store or
Apple's iTunes web page.
Update: Apple has added a feature page
[iTunes Store] to the iTunes Store highlighting iTunes Extras and compatible movies. The page also includes a promotional video for iTunes Extras.
