The recently released critically liked but somewhat slow and elliptical Icelandic move A White, White Day (Hvítur, Hvítur Dagur in Icelandic) is a story about a small town policeman who starts to suspect his recently deceased wife was having an affair and goes a little off the rails exploring the possibility.
Before I watched it I suspected that the title would simple be a reference to Icelandic weather, possibly with some part occurring during a blizzard. This is far from the case and no such obvious reference occurs in the film.
So where does the title come from? Is it alluding to something I missed or something obvious to Icelanders and not to me?
