The man who shows the apartment to Laurence is played by Xavier Dolan's father, Manuel Tadros, just like he did in Dolan's first movie.
When Fred (Suzanne Clément) goes to the event she is invited to, the camera instantly focuses on several guests' faces. One of them is the director, Xavier Dolan, appearing in the film for just a second.
Louis Garrel was originally set to play the title role of Laurence but dropped out. Melvil Poupaud signed on to replace him.
