Seems pretty packed:
• Audio Commentary—Two separate commentaries accompany the original theatrical version and extended version of the film.
• The Scrolls of Knowledge—The original trivia track has been newly enhanced with focus points allowing viewers to access a series of new behind-the-scenes featurettes exploring key scenes and how they relate to the historical accuracy depicted in the film. The extended version of the film also includes a deleted scene marker.
• Visions From Elysium: Topic Marker—Viewers can tag moments of interest throughout either version of the film, allowing them to create “shopping lists” of topics to learn more about. Thanks to the Blu-ray player’s memory, the topics will automatically be loaded when Disc 2 is inserted, giving viewers immediate access to featurettes and galleries of interest.
• Strength And Honor: Creating The World of Gladiator—The definitive documentary on the origin, production and impact of the Oscar®-winning classic. The documentary includes an all-new Enhanced Viewing Mode allowing viewers access to additional interviews and behind-the-scenes material.
• The Making of Gladiator—HBO First Look special.
• Gladiator Games: The Roman Bloodsport—Learning Channel special.
• Hans Zimmer: Scoring Gladiator—An exploration of the rousing soundtrack.
• My Gladiator Journal—Personal diary of the young actor who played Lucius.
• Image & Design—Featurettes and galleries covering the production design, storyboards, costumes and more.
• Abandoned Sequences & Deleted Scenes
• VFX Explorations: Germania & Rome—Shot deconstruction with the visual effects artists.
