Director Robert Jan Westdijk and writer Ronald Giphart found each other in their dislike of the previous film based on Giphart's work, I Love You Too (2001). They decided to work together to make a more faithful adaptation of Giphart's novel "Phileine Zegt Sorry". That is why Giphart has a cameo in the movie where he states that the movie is better than his book.
Tara Elders (Lala) and Michiel Huisman (Max) met on the set of this film. They later married in 2008.
Carice van Houten was originally sought to play Lala, but she couldn't due to theater commitments. Tara Elders was cast instead.
Due to budget issues, the Waldorf Astoria Hotel as well as Gloria Gaynor (both featured in the book) could not be included in the movie.
Neither could David Letterman; like in the novel, Phileine was to be a guest in his talkshow, but since the production could not afford both him and his usual crew, this was changed to Phileine becoming a news item instead.
The setting of the novel was changed from Amsterdam to Utrecht in the movie, which is where author Ronald Giphart lived at the time.
