Just look at most Swedish movie directors, they all have that little bit of Bergman in them, some more than others. I know, was born and raised on the Island of Gotland, an island where nearly everyone used to know each other, with long family ties and history. Of course it's a great place to make a movie or TV-series since Gotland is a "summer heaven" with great weather, good people, great beaches and plenty of places for good food.
