Marvel has released a trailer for the “Avengers: Age of Ultron” Blu-ray edition. The trailer explains some of the Infinity stones that have already been featured in previous movies.

The new video posted on the Marvel’s YouTube channel teases that the exclusive content in the Blu-ray edition will “unlock the infinite six.” The trailer revealed that the stone inside Loki’s scepter is the Mind stone, the Tesseract is the Space stone, the Aether is the Reality stone and the Orb is the Power stone.

The first “Avengers” movie featured Loki’s scepter; the Tesseract and the Aether were featured in the two “Thor” movies; and the Orb was a part of Marvel’s “Guardians of the Galaxy” movie. There are still the Soul stone and the Reality stone that are yet to be revealed in the Marvel Cinematic Universe. It is unclear if the Blu-ray edition will give more details about the two remaining stones.

The Blu-ray will include 45 minutes of exclusive content, which includes behind-the-scenes footage and interviews with some of the cast. Some of the filming locations of the movie will also be shown in the video. The international locations where “Avengers: Age of Ultron” was filmed include Italy, South Korea, Britain and South Africa.

Deleted scenes and a gag reel of the movie will also be a part of the Blu-ray edition. One unreleased clip has been made available to Entertainment Weekly by Marvel. The video shows a scene where the Vision (Paul Bettany) tries to convince the other superheroes that he can be trusted.

The report notes that there will be a “breakdown” about the Infinity stones in the Blu-ray edition of the movie. The stones will be a major part of the two-part “Avengers: Infinity Wars” movies, in which the Mad Titan Thanos will try to acquire all the six stones for his Infinity Gauntlet, which will make him one of the most powerful beings in the universe.

“Avengers: Age of Ultron” 3D Digital and the Digital HD versions will be released on Sept. 8, and the 3D Blu-ray, DVD, Digital SD and the VOD will be released on Oct. 2. There won't be a director’s cut edition.
