Continuity mistake: As Sarah Morton copies the text from Julie's diary, there is a picture of Julie's mother sitting on the crease of the diary between the two opened pages. In the next shot, the picture is sitting to one side of the diary, yet Sarah has never stopped typing out the diary entries and therefore could not have moved the picture.
Swimming Pool (2003)
Ending / spoiler
Directed by: François Ozon
Starring: Charles Dance, Charlotte Rampling, Ludivine Sagnier, Jean-Marie Lamour
Sarah Morton (the writer who is staying at the house) finishes her book and brings it to her publisher. He does not like it, and we find out that the book is the story of the movie - she has made it all up. In the last scene, she meets his real daughter who is nothing like the image created in her story.

Julie: I'm so tired.
Sarah Morton: Not surprised. It's tiring to kill a man.
Trivia: Near the end, the publisher tells Sarah Morton that he is disappointed in her latest book and asks her "Where's the plot twist?" Interestingly enough, the viewer is presented with a very big plot twist a short while later as the movie ends.

Chosen answer: Julie was not the publisher's daughter. Julia, who we see at the end, is the real daughter - given that Sarah doesn't seem very surprised to see Julia at the end (and the reaction of the secretary proves she's known to everyone), the most likely explanation is that the entire sequence in France is in fact the content of Sarah's book, and never really happened.
