In early trailers for Thor: Ragnarok, Hela could be seen destroying Mjolnir in a New York City alleyway. That's not a particularly glamorous location for such an iconic moment to take place but no one really complained at the time. Despite that, a newer trailer for the Marvel Studios threequel revealed that the shocking destruction of the God of Thunder's magic hammer was moved to an open field instead.During an interview with Digital Spy , Thor: Ragnarok director Taika Waititi shed some light on what he changed the scene (presumably during reshoots) and his decision to include Odin and Loki in it.

"Here’s the thing, mate. Here’s the thing: Alleyways aren’t cool, and fields are cool, all right? Ask anyone. We originally shot some of that stuff in a setting that was set for New York, and what we wanted to do was to have them go down to Earth and they see Doctor Strange, but it felt too convenient that he was suddenly just down the road, in an alley, and also everything up until then had been so fast-paced and all over the place, we wanted to go somewhere peaceful and actually chill out with the characters, and be with Odin and pass this wisdom and stuff, and not have to hear stupid yellow cabs honking out the back.
