Continuity mistake: Cecilia and Raymond are on the end of the dock and Raymond turns around and runs. Cecilia then says her line, turns around and runs. In the next shot the two girls are running towards the end of the dock. You can see Raymond running towards them but Cecilia is gone. She should be in the scene running the same way. (01:28:05)
Continuity mistake: When Aquamarine is in Leonard's house after he rescued her from the water tower, the tuckshop lady comes down the stairs outside with a basket of washing and walks away. The camera then goes on Leonard and Aquamarine again, before showing the tuckshop lady coming down the stairs again with the same basket of washing and walking away.
Factual error: The film is based in Florida but several scenes show rocky cliffs and hills not native to the area.
