The history of superhero movies in the Marvel Cinematic Universe features a lineup of lethal villains, among them the long-standing organization Hydra, Loki and Ultron. From this list, it is notable that villainous characters have been dominantly male.

However, Cinema Blend reports that the upcoming third “Thor” movie, “Thor: Ragnarok”, may change that trend by introducing a female villain. Cinema Blend clarifies that nobody has been cast yet for the role but the production team is said to be looking for a “big name”. Among the actresses rumored to be considered for the role include Cate Blanchett and Alice Eve.

Although at this point this casting news may still be a rumor, fans have already been speculating on who among the female villains in the comics will be brought to life in the big screen. According to MovieWeb, the character of Amora, the Enchantress may be the main villain for the third “Thor” movie if the rumors would actually be confirmed. The site also gives a little background about the character.

MovieWeb describes Amora as follows: “Amora debuted in the comics back in 1964, when she was sent by Thor’s father Odin to eliminate Jane Foster, since Odin believed she was distracting Thor.” The site also suggested that since comic heroine Valkyrie is also rumored to appear in the film, it makes more sense for Amora to be the villain because the two are mortal enemies.

According to reports, aside from Amora the Enchantress, another villain called Hela, Queen of the Dead is also rumored to be another antagonist in “Ragnarok”.

Most details regarding the film are still under wraps at this point. However, IGN shares that Mark Ruffalo’s involvement as Hulk is already confirmed for the movie. According to the site, Thor and Hulk will team up and get into “a cosmic road trip.”

“Thor: Ragnarok” will star Chris Hemsworth, Tom Hiddleston and Mark Ruffalo. It will film in Australia next year and is set to premiere on November 3, 2017.
