When Jacob meets Helene, during the wedding, his hairstyle changes multiple times between scenes.
When the couple gets married, the rings are placed on the fingers, but no visible in scenes post marriage. The customs in Denmark may be different, but throughout the film, wedding bands, rings, etc. migrate from hand to hand (wedding band on the right hand for women, left for men), and also disappear.
In their first business meeting, Jørgen tells Jacob he intends to create a dedicated fund, but mispronounces it "decidated" (in Swedish: "deciderad" instead of "dedicerad").
