Thor Ragnarok Trailer Breakdown: 23 Things You Must See

22. Welcome To Hel?

So is Thor in Hel here? Has he been sent here by Hela after their first entanglement?

Or maybe this could this be Muspelheim, home to the demon Surtur, whose presence was first seen as concept art at Comic Con, as revealed by ComicBook.com:

“The shot is early; they've literally been shooting this film for five days, and this is probably test footage. Hulk is roaring, jumping from some crazy height, ready to fight. As he dives to what's below him, everything around him is on fire - and that's when you realize, there's a face, and out of that face a louder scream than the Hulk's. It's Surtur, the fire demon of Muspelheim.”

Fans also picked up on what appeared to be his horns from this image...

Strictly speaking, it could be either or both - an amalgamation that is both Hela's homeland and where Surtur lives. Not a very welcoming place, either way.

If this is Hel, it would explain why there are zombies - as teased in some of the green screen filming images...
