Jalouse is a 2017 French comedy film directed by David and Stéphane Foenkinos.
Plot
Almost overnight, Nathalie Pêcheux, a divorced French teacher, changes from a loving mother into a jealous monster. Her first target is her stunning 18-year-old daughter Mathilde, a ballet dancer, but her field of attack soon extends to her friends, colleagues, and even her neighbours. After the success of their film Delicacy, author and screenwriter David Foenkinos pairs up again with his brother Stéphane Foenkinos to portray a woman's radical and unexpected shift of character that oscillates between black comedy and psychological thriller.
