Lisa Azuelos both wrote and directed this film after realizing that movies based on teen life in her home country of France were almost entirely missing. She would often see her daughter go to the theatre to watch either an American teen movie or a horror film.
In the scene where Charlotte and her mother meet the math teacher in the supermarket, "Reality," performed by Richard Sanderson and composed by Vladimir Cosma, is playing in the background. "Reality" is the main song of The Party (1980), Sophie Marceau's debut film.
Jocelyn Quivrin, who played "Lucas," the narcotics detective dating Lola's mother Anne in LOL (Laughing Out Loud) (2008), died on November 15, 2009 in Saint-Cloud, Hauts-de-Seine, France as the result of an automobile accident. He was survived by his wife and eight-month-old son.
An American remake LOL (2012) released on May 4, 2012 starring Miley Cyrus, Demi Moore, Ashley Greene, Adam Sevani, and Douglas Booth was a critical and commercial failure.
