Award season is great for many reasons – we get to honour the best in the business, possibly hear about movies that we wouldn't have otherwise and watch actresses walk down the red carpet and pose in beautiful dresses, among other things. However, it is the red carpet interviews that give us the meat on what Hollywood will offer us in the future.
During the BAFTA red carpet interview with ET, Mark Ruffalo aka Hulk said that he was excited to have Cate Blanchett join the Marvel Universe. She is supposed to have a very significant role in the upcoming "Thor: Ragnarok". While she is yet to confirm the news – having once dodged the question when Jimmy Kimmel asked her about it – according to Ruffalo, she will be playing a "baddie".
At this point in the "Thor" trilogy, there are three huge female villain characters that Blanchett can play, and they are the Enchantress, Karnilla and Hela.
Enchantress is a huge supporter of Loki and in comics, has even served as his lieutenant during his brief tenure as the ruler of Asgard. Tom Hiddleston, who plays Loki, has mentioned more than once that he would love for his character to work with Enchantress in the movies.
Fans, however, suspect if Enchantress would actually appear in the movies, because a version of the villain has already debuted in Marvel's "Agents of Shield".
Karnilla, who is interestingly Enchantress' teacher in magic, is the Queen of Nornheim, an Asgardian province. She has sided with Loki in many of his evil quests, although she is deeply in love with Thor's other brother Balder the Brave.
If she does appear in the movie, Karnilla will be the key to triggering Ragnrok. She perhaps will also be seen manipulating Loki to do her bidding so that she can ensure the destruction of her mortal enemies, the Asgardians.
Hela is the Goddess of Death and ruler of Hel and Niffleheim, Asgardian version of the underworld. According to the comics, when an Asgardian dies he/she goes to a physical space called Hel, meaning they can crawl their way back into the world of the living.
If the character of Hela is introduced, it would be interesting for the "Avengers: Infinity War" movies, because Thanos, the villain of those movies, is said to be in love with the Goddess of Death. She, however, is not interested, and it is to impress her that Thanos is looking for the infinity stones.
He assembles the infinity gauntlet and with the snap of his fingers almost half of the living beings in the universe is killed. He believes this will attract the Goddess of Death.
Note that, Thanos in the comics is attracted to Death, who is not the same as Goddess of Death. However, if "Thor" were to introduce Hela in "Ragnarok" she will act as proxy Death in the series.
