The Lesson is a 2023 British psychological thriller film written by Alex MacKeith, directed by Alice Troughton and starring Richard E. Grant, Julie Delpy and Daryl McCormack.

In the way that the movie is structured, it is similar to a play: there are only five key characters and almost the entire story takes place in one location.

The story is centred on the interaction between the four main characters: an Oxford student employed as a tutor by a wealthy family living in a mansion in the countryside; the teenage son who will be tutored by the Oxford student; and, finally, the son’s parents, who are a famous British writer and his French wife, an artist. The family employs a near-silent and enigmatic butler, who is the fifth character: the person who sees everything but says nothing.
