The French title "Les Petits Mouchoirs" refers to an idiomatic expression that is similar to the English term "Sweeping something under the rug". You cover something up with a napkin or a handkerchief and pretend it's no longer there even though everyone knows it is. The English term "Little White Lies" is a similar if not identical concept.

The film was France's highest-grossing film in 2010, with more than 5 million tickets sold.

The movie that Eric and Marie are watching is Scarecrow (1973), with Al Pacino and Gene Hackman.
