A good portion of the first two Thor movies were set on either Earth or Midgard, as other places in the nine realms made shorter (but signifiant) appearances. That should be changing with next year's Thor: Ragnarok. The movie has been described as a cosmic, buddy road trip featuring Thor and the return of Mark Ruffalo as Hulk. Marvel Studios head Kevin Feige has similarly claimed that there is "very little Earth" in Ragnarok.
Production on Ragnarok is already well underway in Australia, with leaked set photos having thus far shown the creation of Asgard via practical sets. The movie will explore far more than just Asgard, of course, and that appears to include some familiar territory for Thor, Hulk and Thor's adopted brother Loki (Tom Hiddleston) too.
The Sydney Morning Herald has posted new photos of the sets that are being built for Thor: Ragnarok as production moves into a more public place for the next week. Revealed in the set photos is a return to New York City for at least some of the characters. It is unclear at this time who will be on hand to film on the makeshift New York sets, but the combination of taxi cabs, ambulances, and other decor show the beginnings of what will be filmed their in the near future.
As filming on the New York scenes start this week, it would not be surprising to see more of these photos released in time. It's possible that Loki and/r Thor make their return to Earth in these scenes; though with Ruffalo having already wrapped filming, the Hulk could be missing out on this trip back home. If the scenes do include one of the main characters coming to Earth in the middle of their adventure, it could be to find someone who has been reported to have found his way to Earth on his own. If that is the reason for Thor, Loki, or someone else to return to Earth, it should make for an interesting encounter.
However, whatever is being shot here is likely not going to be a big fight scene or a center piece in the movie. After all, New York is stuffed with superheroes at the moment - what with Doctor Strange, Spider-Man and the Defenders among those in-state. In fact, Doctor Strange, Spider-Man: Homecoming, and possibly even The Defenders will be released before Thor: Ragnarok - so if another major Marvel Cinematic Universe cameo is in play here, this would be the time to have it.
