"Pelle Svanslös i Amerikatt" spends nearly half of its screentime on a fever dream about America. The main character hears that America is a land of opportunities where everything is bigger, so he has a dream where he imagines what that might be like.

The only real American in the movie is the cat in this picture. Everything else is just part of the dream. The dream segment takes place at about 16:00-47:00.
