That’s because we’ve got our first look at Benedict Cumberbatch as Doctor Strange as he appears in the film. We’ve known that the Sorcerer Supreme would appear in Thor: Ragnarok since the end credits scene in last November’s Marvel release, Doctor Strange. In that film we saw Doctor Strange taking a meeting with Thor in his Sanctum Sanctorum and confronting the god of thunder about his brother Loki, who was leading Asgard in the absence of Odin, but now both were on earth. Doctor Strange wanted to help Thor get all Asgardians off of the Earthly plane.
The trailer starts with Doctor Strange in his Cloak of Levitation appearing to Thor in his Sanctum, hovering above the ground, as he warns him that he senses a great change in his future and that “Destiny has dire plans for you.”
If you guys need to find me, I’m dead on the floor now, so good luck.
The way the trailer is paced and the way they’ve structured the story they’re telling, it seems that Thor’s interactions with Doctor Strange take place at the beginning of the film. In fact, it’s entirely possible that Doctor Strange sends Thor on a collision course with Hela, the goddess of death as played by Cate Blanchett. If this is the case, that would answer just what exactly Doctor Strange’s role is in this particular Thor story.
The rest of the trailer seems to play out the way the SDCC trailer did, just with a couple extra seconds here and there of scenes we’ve already seen. For instance, we’ve already seen Heimdall (Idris Elba) fighting in that wooded glen, but we get a brief bit more of his sword swipe. And, of course, we’ll take any chance we can to see Hulk grinning at the prospect of smashing and Valkyrie (Tessa Thompson) nonchalantly sashaying into battle, confident that no one is getting in her way.
