Revealing mistake: When Hallie is about to pierce Annie's ear, Annie puts the apple underneath her earlobe and Hallie puts the needle in - you can clearly see that Annie's ear already has a hole in it. (00:40:39)

The Parent Trap (1998)
Plot summary
Directed by: Nancy Meyers
Starring: Dennis Quaid, Lindsay Lohan, Natasha Richardson, Elaine Hendrix
Pre-teen identical twins Annie and Hallie
Nick Parker: You two help Meredith.
Meredith Blake: Sure you'll help me. Right over a cliff, you'll help me.
Hallie Parker: Not a bad idea.
Annie James: Yeah, see any cliffs?

Trivia: The actor who plays the boy accidentally placed at the all-girls camp is Lindsay Lohan's brother.
Question: Towards the end of the movie, when the parents are looking at the wine bottles, they hear Martin and Chessy arrive home. Nick tells Elizabeth "she has a key" - why does Elizabeth back up right away as he said that?
Answer: I think she was scared of falling in love with Nick again, and maybe because she thought they were better off not together, considering they became successful and achieved each other's dreams when they were apart.





Suggested correction: I've looked at it closely. I can't see a hole anywhere.
You can also see that Annie's ear is already pierced during the lake scene.
