iTunes 11.3 Adds support for extras in HD movie purchases
iTunes Extras include content that offers more to go along with iTunes Store movie purchases such as behind-the-scenes videos, short films, high-resolution image galleries, director's commentary, scenes, and more. HD extras will be available at no cost for movies you have already purchased.
iTunes is free and available for download at the Apple website. The 11.3 update can be installed via Apple's Software Update app, or downloaded at the Apple Support website.
