- The first film in Lars von Trier's third trilogy series entitled "USA - Land of Opportunities". The two other parts are Manderlay (2005) and Wasington (2009).
- Was a critics' favorite to win at the 2003 Cannes Film Festival, but received no prizes.
- A fifteen-minute pilot film was made in the pre-production phase to test whether the concept of chalk lines and spare scenery would work. The pilot starred Danish actors Sidse Babett Knudsen and Nikolaj Lie Kaas. Dogville: The Pilot (2003) (V) is featured on the 2nd disc of the Dogville (2003) DVD, released in November of 2003.
- The famed introductory scene of Dogville seen from above was in fact generated by a computer from 156 individual shots. The ceiling of the filming studio was actually not tall enough to make one single, wide shot from above possible.
- Nicole Kidman is said to have communicated very little with the rest of the team, apart from practical issues. However, she did invite the team for champagne and caviar and flew in Mexican chefs to cook for everyone.
- Katrin Cartlidge was chosen to play Vera, but she had to leave the shooting because of her health problems.
- 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").
- The pictures shown in the end credits are from Jacob Holdt's book/documentary American Pictures (1984)
- Inscribed on the entrance to the old mineshaft is the Latin motto "Dictum ac factum", which can be translated as "No sooner said than done".
- Paul Bettany didn't want to play Tom Edison because they were shooting it in Sweden. Then his friend Stellan Skarsgård said that Lars von Trier's shoots are 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 will start, 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"
- When Nicole Kidman went to Sweden to shoot this movie, it was the first time in 15 years that she had flown on a public plane.
- 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.
