Corrected entry: In the scene after Joel drops his parents off at the airport, he pours himself a whisky and coke. During the closeup he is pouring "New Coke" into the glass but when the shot changes he is setting down a can of Coca-Cola Classic.
Corrected entry: In several instances in the film, it is stated that Joel scored a 597 on the Math portion of his SATs. SAT scores are always multiples of ten. He could have scored a 590 or a 600, but not a 597.
