When it comes to the ruling family of Asgard, perhaps father really does know best. It turns out Odin, king of the gods and former ruler of Asgard, was aware of certain major looming cosmic dangers that both Thor and his treacherous stepbrother Loki weren't when the latter usurped Odin's throne at the end of Thor: The Dark World.

During my visit to the set of Thor: Ragnarok last year, producer Brad Winderbaum revealed how Loki's (Tom Hiddleston) power play may have won him all he wanted in the short term, but ultimately proves a big problem once the goddess of death Hela (Cate Blanchett) returns to threaten all existence. The movie will reveal Loki banished Odin (once again played by Sir Anthony Hopkins) to Earth, where Thor (Chris Hemsworth) and Loki will end up seeking him out as he wanders the streets of Manhattan.Winderbaum explained that "what Thor comes to learn early on is that there's a lot of terrible things in the cosmos that just shouldn't be that way. And we learn that Odin was doing far more than it seemed on the surface to keep the universe safe. That there were all these threats that he had quelled or was keeping at bay, using his strength and power to do so, that Loki was completely unaware, unprepared for."Winderbaum also said that while the trickster god "achieved his goals" in finally winning the throne, it proves a bittersweet victory for Loki: "So he becomes the King of Asgard, everything is great, it's a good party, but he failed to realize the threats that were just over the horizon, Hela being the biggest and most terrible one of all."For his part, Loki actor Tom Hiddleston stressed that "Loki's feelings towards his family members are complex" and that he "never conceived of Loki's emotional connections to Odin or Thor as malevolent. He just wants to have a go, on the throne, which he does."Ultimately, Loki and Thor must team up with Hulk and Valkyrie to take on Hela. Loki, however, will find much to his surprise that his Avenger sibling has moved on from the heightened emotions that defined their past relationship, something Loki struggles to deal with.Chris Hemsworth said during a break in filming that, after Thor tried to either save or stop his brother in past films, "there’s a feeling from Thor now that’s just like, you know what, kid? Do what you want. ... You’re a screw-up, so whatever. Do your thing."That leaves Loki flummoxed. As Hiddleston explained, "The opposite of love is not hate but indifference. So the idea that Thor might be indifferent to Loki is troubling for him, because that's a defining feature of his character is, I don't belong in the family; my brother doesn't love me; I hate my brother. And the idea his brother's like, yeah, whatever, it's an interesting development."Their fraternal bond will ultimately prove vital to the plot of Thor: Ragnarok. Hiddleston said "that's what I kind of loved about Ragnarok when I first read it, the two of them are placed in such an extraordinary situation where everything is unfamiliar; that their familiarity, literally, as family members becomes important."For more on IGN's trip to the set of Thor: Ragnarok, check out these 9 details we learned about the Hulk , what we can (and can't) reveal about the climactic bridge battle , and then feast your eyes on these 8 new posters that pay homage to the distinctive style of iconic Marvel artist Jack Kirby!
