Script written from April 2010. The main actress was found on the first day of casting. The film was shot in twenty days in August 2010 with a crew of fourteen.
The scene, so delicate, of Laure's nudity and the revelation that follows, was consciously put in place by Céline Sciamma. This scene is pivotal, and Zoé Héran knew from the script that she would have to shoot naked. Her parents were present at the time of filming, and this intense moment could only exist in the image with their consent in view of the filmed sequence.
Céline Sciamma, the writer and director, said "I made it with several layers, so that a transsexual person can say 'that was my childhood' and so that a heterosexual woman can also say it." She also said the "movie is ambiguous about Mickaël's feelings for Lisa. It plays with the confusion."
In 2017, it was ranked by IndieWire as "the third best lesbian movie of all time."
