Corrected entry: When we first meet Robin Penn, in the restaurant where she works, her right front tooth is noticibly chipped. When we see Robin at the end of the movie, her tooth is whole. No cosmetic dentistry visits between scenes were mentioned.
Corrected entry: Before he leaves for his Baja fishing trip, Jack Nicholson's character sits at an airport bar drinking a plastic cup of Scotch. As the camera pulls away in the next frame, he's shown sitting in front of a tall flute of beer. A few frames later, he's back in close up, nursing his short plastic cup of scotch.
