Brilliantly constructed / References.
To start with, let me say what a brilliant movie it is, out of nowhere and saving a rather frustrating day!
As the movie "unrolled", it reminded of what Kundera used to do (I think in "The Joke") or Coupland in "Hey Nostradamus" -or even Easton Ellis in "The Rules Of Engagement"; check them out: you have the same story or episode, then re-narrated by various characters from their different points of view. Obviously, the classic Japanese cinema reference here would be "Rashomon"!
There was another Scandinavian movie, about 10 years ago, whose title escapes me but was smtg like "Scenes From A Cold Country": if you liked "Confessions", you should like it too. It also started with a crime story (a heist gone wrong) ...and then explained what happened to its characters afterwards as they came to terms with the original plot.
