Australian star Chris Hemsworth's superhero becomes possessed by the Norns in the clip, and Dr Erik Selvig (Stellan Skarsgard) learns more about the Mind Stone - which would eventually give life to Vision, reported Digital Spy.
The Norns also prophesise that a human sacrifice must be made to defeat Ultron.
The scene features on the "Avengers: Age of Ultron" DVD and Blu-ray, which was released earlier this month.
The DVD's release caused controversy after Black Widow was carefully removed from the cover.
