Chosen by "Les Cahiers du cinéma" (France) as one of the 10 best pictures of 2007 (#05, tied with "Zodiac")

Bozon stated in a Cinema Scope interview that the film was shot using "a film stock never used before to shoot a movie, Kodak 5299, which is usually used as an intermediate film in numerical post-production." This was used to achieve the so-called "aquarium feeling" of the film's night scenes.
