Other mistake: When Adam picks up Emma and is leaning against his car, he pulls a "bouquet" of carrots from behind his back, but just prior he had nothing in his hands.

1 other mistake
Directed by: Ivan Reitman
Starring: Kevin Kline, Cary Elwes, Natalie Portman, Ashton Kutcher, Lake Bell
Factual error: When Aston Kutcher is calling every girl in his address book he is using an iPhone. In one of the shots you can see the screen lighten up as he's chatting to the caller. If he was really on the call, iPhone would switch off display in proximity to ear to avoid unwanted key strokes and save battery.
Shira: We're sluts, Emma! We're dirty dirty sluts!
