Anecdotes

At the beginning of the film, Malmberg (a Swede) becomes ill after having to drive on the right side of the road in Norway. Today both countries drive on the right. In 1967, Sweden switched to the right because making two versions of cars like Volvos and Saabs for domestic and foreign sales was inefficient. Also, there are many unguarded, unmarked border crossings points (unlike the crossing in the film); people would not realize which country they were in and sometimes ended up driving on the wrong side.

Throughout the film, Isak speaks Norwegian and Folke speaks Swedish; this is true even when they are having conversations with each other.
