Thanks to superherohype.com, we have the plot for Thor: Ragnarok. The film will showcase Chris Hemsworth as Thor, the God of Thunder, Tom Hiddleston as Loki, Mark Ruffalo as the Hulk, Idris Elba as Heimdall, and Sir Anthony Hopkins returns as Odin. New ads to the franchise include Cate Blanchett as the death-obsessed Hela, Jeff Goldblum’s eccentric Grandmaster, Tessa Thompson as hero Valkyrie and Karl Urban as Skurge. …
Plot: Thor will arrive in Asgard after hearing about trouble in his home world, and when he arrives he finds Loki’s style of ruling (while impersonating Odin) has led to some lapses in the rules and leads to the freeing of prisoner Hela. Thor and Hela naturally come to blows when they meet, which sees Thor “blasted” to Sakaar, described as “a barbaric planet ruled by the charming but nefarious Grandmaster (Jeff Goldblum).” There he meets Valkyrie, who is hiding out on the planet, and brings him to the Grandmaster to make him a gladiator, where he meets the most popular competitor in the arena, The Hulk, and loses his trademark hair and hammer.
