Producer Kevin Feige said, "[W]hile Thor was a fish out of water on Earth in the first two films (Thor and The Avengers), this time Jane is very much a fish out of water in Asgard." Portman added, "It was a whole different adventure this time. Because Jane is the fish out of water. I didn't want to make it like Bill & Ted, or like a valley girl dumped into Shakespeareland."
