Continuity mistake: When Andy is talking to her boyfriend while doing the science project, she picks up the bottle of beer while getting up to go and hug him. The bottle disappears when the scene cuts to the hug.
Suggested correction: Given that how the shots change, it's likely that she would have put it on the desk again.
Corrected entry: When Andy goes to the fashion party on Nate's Birthday, her hair ornament is a white butterfly, but when she gets home it has changed to a white flower.
Correction: No, it is a white flower all the time.
Other mistake: Andie lives at Broome and Orchard, in the heart of the Lower East Side. Average rent for a one-bedroom apartment (which they have) was $2217 at that time, and Nate and Andie both make barely minimum wage. That rent would have taken their *entire* combined salary in 2006. They didn't depend on help from their parents, since Andie's surprised when help arrives. And the apartment wasn't rent-controlled; Andie and Nate aren't from New York.
Suggested correction: This submission is making assumptions. When is it stated that both Andie and Nate are earning "barely minimum wage"? They may not be upper-middle-class, but their two incomes are never described as "barely minimum." In one scene, the friends raise their drinks in a toast to "jobs that pay the rent." Also, Andie might be surprised to receive money from her father, but we know nothing about Nate's family.
