Don't Look Back (French: Ne te retourne pas) is a 2009 French thriller film directed by Marina de Van and starring Sophie Marceau and Monica Bellucci.

[2] Written by Jacques Akchoti and Marina de Van, the film is about a wife and mother of two children who suddenly notices changes to the way the family home is arranged and feels that her body is transforming without anyone around her noticing it.

While others believe her perceptions are due to fatigue and stress, she is sure that something more profound is happening, and her search to understand these mysterious perceptions prompts her to track down a woman in Italy who holds the key to the mystery.

[3] Jeanne, a married woman with two young children, starts to notice small changes taking place in the arrangement of objects in her family's home—furniture, pictures, rooms—as well as in her physical appearance.

Feeling increasingly out of sorts, ever more distant, and even psychologically cut off from her husband and children, who are baffled by her behavior, Jeanne goes to her mother in the hope that she, at least, will provide for her some clarification or otherwise soothing solution.
