“Thor: Ragnarok,” out Nov. 3, reunites Chris Hemsworth’s hero with Tom Hiddleston’s Loki.

Loki might be to blame for the reappearance of Cate Blanchett’s Hela, the main villain in this film.

After seemingly losing a confrontation with her, Thor finds himself in Sakaar, a planet ruled by none other than Jeff Goldblum’s Grandmaster.

Thor is forced to become “a gladiator” and runs into the Hulk played by Mark Ruffalo.

Doctor Strange, Idris Elba’s Heimdall, Karl Urban’s Skurge will make cameos.
