Paul Bettany didn't want to play Tom Edison because they were shooting it in Sweden. Then his friend Stellan Skarsgård told him that Lars von Trier's shoots were so funny that "you'll miss something extraordinary if you turn the part down". After shooting half the movie Bettany asked Skarsgård when the fun would start, to which Skarsgård replied: "I lied. I did it because he is amazing to work with, and you wouldn't be able to see that before you were actually here yourself. I wanted to give you a chance, and you wouldn't have shown up if I had been frank with you."
Nicole Kidman reportedly vowed she would never work with Lars von Trier again after completion of the film. Kidman later turned down the lead in his film Antichrist (2009), but in late 2010 revealed that she and Trier were still in touch and in 2012 she was cast in his film Nymphomaniac: Vol. I (2013), but left the production due to scheduling conflicts.

Jeremy Davies originally intended to be von Trier's apprentice, not to act in the film. He wrote a letter to the director stating that he plans on being a filmmaker and wanted to learn from him. von Trier invited him to the set, mentored Davies, and gave him a small role in the film.
According to Lars Von Trier, Russell Crowe visited the sparse and entirely unique set one day and said, "This demands an explanation," to which Von Trier, in the spirit of Dogme '95, said, "Not from me."

Inspired by Bertolt Brecht's "Ballade von der Seeraeuber-Jenny" ("Pirate Jenny or Dreams of a Kitchenmaid", Music by Kurt Weill) in the "Threepenny Opera". Grace actually quotes from the song once, when she says the coming night no one would sleep in the bed she makes ("es wird keiner mehr drin schlafen in dieser Nacht").
Paul Bettany, who only took the part of Tom Edison after being convinced by friend Stellan Skarsgård, later called the making of the film "hideous" and "a peculiarly unsatisfying experience because [Lars von Trier] has no interest in you being any part of the cerebral process with him. You're absolutely his puppet." Despite still being a fan of von Trier's films in general, Bettany has never watched the film and has no intention of ever doing so.
Aspiring filmmaker Jennifer Kent felt she could learn more from working Lars von Trier than by attending film school and hereby reached out to him in order to work on one of his films.

During production, Lars von Trier and Nicole Kidman would go hiking in the snow together and drive around in Trier's camper van and he would challenge her with questions on her religion, her philosophies and her ideas about life.
