The restaurant that Reggie Perry and Desiree Stokes Perry stop at to get directions at is at an actual motel in Yulee, Florida. The beach store that is supposedly across the street is actually several miles away on Ameila Island.
On shooting location, a road was being blocked and a couple of patrons could not get to a bar across the street until the crew was done shooting that particular scene. While in the middle of filming a scene, one man furious with waiting runs across the scene and moons the camera, eventually making it to the bar safely.
Early in the film when Francine is talking with one of the developers, they pass a sign in the foreground that says "Amelia Island", the filming location, instead of the film's fictional location, Plantation Island.
During the conversation between Desiree and her mother on the beach, the door to the house is suddenly closed, though there is no evidence of anyone having closed it and it makes no sound.
