“Rob had made two movies, quiet intimate movies.
If you look atThe Lighthouse two dudes in a lighthouse.
And then suddenly, you have a big action-adventure film.

No one had told Rob how to make a big action-adventure film in a conventional way.
It proved both an exhausting and inspiring experience.
“It’s an undertaking that is almost borderline insane,” Skarsgard says.

He continues, “Again, it demanded a lot of everyone.
Because if we were a split second too fast, we were not in frame.
A split second too slow, we were also not in frame.
So it was about finding that.
But I think everyone thought this was an absolutely insane idea, but also, it triggered everyone.
Everyone got really excited about telling a story in this way.”
The chickens and the horses, however, could not be reached for comment.
The Northmanhits theaters April 22.
