Being 17 (French: Quand on a 17 ans) is a 2016 French drama film directed by André Téchiné and starring Kacey Mottet Klein, Corentin Fila and Sandrine Kiberlain. The script was written by Téchiné in collaboration with Céline Sciamma. The plot follows the romantic and sexual awakening of two seventeen-year-old boys as their initial animosity, expressed in violence, morphs into love. Being 17 borrows its title from the second half-line of the first verse of Roman, (1870) by Arthur Rimbaud: On n'est pas sérieux quand on a dix-sept ans.
