Thor 3 is being made, although it doesn’t have a confirmed release date or plot yet.
People are speculating about what will happen in the film, such as whether it will include the apocalyptic Ragnarok.
Writer Darren Franich in a wish list for the movie says that Loki should become “the real bad guy.”
In Thor 2, or Dark World, Loki and Thor had to team up to fight the Dark Elves.
At the ending, we saw [spoilers] that Loki had assumed the throne of Odin, taking over Asgard.
“Among a certain kind of hyper-engaged fan, Loki might actually be the most popular character in the Marvel Cinematic Universe — a popularity that Hiddleston seems to relish and gleefully feed,” Franich wrote. “The natural instinct would be to soften Loki’s edges, and to once again introduce a new species of Make-Up Monsters Gone Wild, like Thor 1‘s Frost Giants or Thor 2‘s Dark Elves. Probably the most commonly-demanded villain for a Thor sequel is Surtur, the mega-demon whose purpose is to bring an end to, like, everything. In the comics, Surtur’s arrival actually led Thor and Loki to, yes, team up for the common good.”
“But where’s the fun in that? Let’s give Hiddleston the chance to go Full Lannister as the main villain of Thor 3. The movie absolutely should introduce some colorful new villainous characters … but Loki should be their ringleader. (Even in The Avengers, he was just a forward representative for Thanos.) By the time Thor 3 hits, Loki will have had months or years to secure his power in the Golden Realm. Don’t you want to see what post-Loki dystopian Asgard looks like? Wouldn’t a Thor movie pack a bigger wallop if it came down to Thor vs. Loki, instead of Thor vs. That Guy With The Ears And The Red Stuff?”
Marvel previously announced that Craig Kyle, who executive produced “Thor” and “Thor: The Dark World” will return as a fulltime screenwriter, collaborating with Christopher Yost to create Thor 3.
Among Kyle’s credits is helping create X-23, a young female clone of Wolverine who was introduced into the comic book world. He’s also helped write some of the X-Men comics with Yost.
