Who You Think I Am is a French psychological thriller film released in 2019, directed by Safy Nebbou and starring Juliette Binoche as the lead character, Claire.
Claire is a middle-aged divorced literature teacher who is struggling to come to terms with her recent breakup with her younger lover, Ludo. Feeling lonely and vulnerable, she creates a fake Facebook profile of a 24-year-old woman named Clara, using a photo of a pretty young brunette.
Through her fake profile, Claire begins to engage with Ludo's roommate, Alex, who soon becomes obsessed with her online persona. As the relationship between Alex and Clara deepens, Claire finds herself caught in a dangerous and manipulative game of cat and mouse.
As the lines between reality and fantasy blur, Claire's mental state begins to unravel, and she becomes increasingly addicted to the online persona she has created. The film explores themes of identity, loneliness, and the dangers of social media.
The supporting cast includes François Civil as Alex, Nicole Garcia as Claire's therapist, and Charles Berling as Claire's ex-husband. The film was well-received by critics, particularly for Binoche's performance as the troubled protagonist.
