Corrected entry: When Lindsay has just run across the field to talk to Ben, she isn't out of breath at all. After running the length of an entire baseball field, she should be breathing heavily.
Corrected entry: When they show Ben on TV he is in Florida. In the background there are many different kinds of trees, even ones that don't belong in Florida, but there is not one palm tree.
Corrected entry: In the "Opening Day" scene, everyone is wearing shorts and t-shirts. Opening day in 2004 was April 9th and game time temperature was 52 F. Not really t-shirts and shorts weather.
Corrected entry: Towards the end of the movie it shows Drew Barrymore running across the baseball field. This was also broadcast on T.V. as it shows her surprised parents watching it live. The only problem is when a fan jumps on the field during a real game, the camera pans away from them to discourage anyone from trying this stunt thinking they will get on T.V.
Corrected entry: While eating the lobster dinner with her parents, Ben must have had his ears covered so he did not hear the results of a Red Sox game that he supposedly had recorded. This is impossible as he makes it clear that he has never missed an inning (until a later game, when his friend calls to say they came back in the ninth inning with 8 runs). He had to have watched it on TV or heard it on the radio while it was live.
