The Parent Trap (1998)

Continuity mistake: When Hallie arrives in San Francisco she is shown getting out of the car and the door is closed, then in the close-up shot the car door is open in the background.

Trivia: The actor who plays the boy accidentally placed at the all-girls camp is Lindsay Lohan's brother.

Continuity mistake: When Hallie wants to get a popsicle/lemonade, her hair bobble is green, but in the next shot it is white and then changes back to green again. (00:24:30)
