'Thor 3' Cast, Plot And Release Date Rumors [SPOILERS AHEAD]: Thor Rips Loki's Head Off And Causes Asgard's Demise? New Movie Names Tony Stark As The New Villain? Amora The Enchantress Joins Cast

Marvel has yet to confirm "Thor 3" cast, plot and release date rumors circulating online.

As far as the interwebs and fans are concerned, it seems that "Thor 3" is already a done deal. Just recently, Screen Crush has confirmed that Marvel is indeed pushing through with "Thor 3," and has in fact, already hired screenwriters. One of which, is Marvel's former Senior Vice President for Production and Devopment Craig Kyle.

Kyle will be working on the "Thor 3" screenplay with Christopher Yost who has already written for "Thor: The Dark World."

Speculations have been made that "Thor 3" will feature a well-known character in the comics- Amora the Enchantress.  This early, "The Wolf Of Wall Street's" Margot Robbie has been suggested to play the role of the sexy enchantress.

Aside from this possible addition to the movie's powerhouse cast, the third "Thor" movie is said to show Asgard's demise.

According to "Thor 3" cast, plot and release date rumors published on Movie Pilot, Asgard could come to an end because of Chris Hemsworth's Thor as a part of the "apocalyptic comic book story of Ragnarok."

"After ripping off his brother Loki's head, Thor goes to Muspellheim to meet Surtur after he shattered his hammer and carrying his brother's head," an article in Fashion & Style said.

"The fire giant wants to know whether Thor wants a final battle, but Thor instead convinces Surtur to allow him to reforge his hammer," the website added. "In exchange, Thor smashes down a mountain and lets Surtur lead his army of fire demons onto Asgard. The Norse Valhalla is consumed in fire."

"Thor 3"cast, plot and release date rumors have been going around for quite some time now that the new flick will be following the Ragnarok storyline.  Some experts suggest that if this were true, Tony Stark might have a hand in it too.

Moviepilot speculated, "Ragnarok has dual meaning in the Marvel Comics. On one hand, you have the saga, Ragnarok, which was the Asgardian Apocalypse, the end of their world. If Marvel decided to go this route, Loki would probably have some sort of hand in starting the Asgardian end of days, and Thor would have to not only fight his Brother, but would also have to save his entire world from destruction."

"On the other hand, however, you have Ragnarok. A cyborg clone or Thor himself created by Tony Stark combining his own DNA with Asgardian DNA to replace Thor with the real Son of Odin was MIA."

With the new Ragnarok angle surfacing, fans are left to wonder which Ragnarok is Marvel going to use for "Thor 3?" Or the better question is, will they be going with the said storyline?
