The film follows Liam (McCormack), an aspiring and ambitious writer who accepts a tutoring position at the estate of his idol, J. M. Sinclair (Grant), a renowned author who is working on a new novel. Liam hopes to learn from Sinclair and impress him with his own work, but soon he realizes that he is trapped in a web of family secrets, resentment, and retribution. Sinclair, his wife Hélène (Delpy), and their son Bertie (McMillan) all guard a dark past, one that threatens Liam's future as well as their own.
The Lesson is a gripping and suspenseful film that keeps the audience guessing until the very end. The film plays with the themes of writing, creativity, plagiarism, identity, and manipulation, and questions the boundaries between fiction and reality. The film also features some stunning cinematography by Anna Patarakina, who captures the contrast between the beautiful and serene countryside and the tense and claustrophobic atmosphere inside the estate. The film also benefits from a clever and haunting score by Isobel Waller-Bridge, who creates a sense of unease and mystery throughout the film.
The cast delivers outstanding performances, especially Grant, who portrays Sinclair as a charismatic, eccentric, and ruthless mentor who toys with Liam's emotions and ambitions. McCormack is also impressive as Liam, who undergoes a transformation from a naive and eager student to a desperate and conflicted victim. Delpy adds another layer of complexity to the film as Hélène, who is both a supportive and suspicious wife, and who has her own secrets and motives.
The Lesson is a film that will appeal to fans of psychological thrillers, literary mysteries, and character-driven dramas. The film is a masterclass in writing and deception, and a lesson that some stories are better left untold.
