Another extra from Marvel Studios' "Iron Man 3" Blu-ray release has made it online, a "Thor: The Dark World" behind-the-scenes featurette.

There's not much in the way of new clips here, with much of the imagery already seen in previous trailers. Actors Chris Hemsworth (Thor), Tom Hiddleston (Loki), Natalie Portman (Jane Foster) and director Alan Taylor each discuss elements that excite them about the film, including a new role for the title character.

"Thor is stepping into the role of king, and coming to terms with the responsibilities that becoming king carries," Hemsworth said.

"Thor: The Dark World" is in theaters Nov. 8. "Iron Man 3" is out on Blu-ray, and DVD on Sept. 24, and as a digital download on Sept. 3.
