Factual error: When Jess arrives late at the final match, she is brought on as a substitute. Yet, the referee should know about the possible substitutes before they are brought on - he didn't even know about Jess. Jess said she wouldn't be able to make the match due to her sister's wedding. Therefore, she would have been removed from the team line-up.
Factual error: When Bullock and Grant are stuck in traffic they are on the ramp of the upper level of the Queensboro bridge. No trucks are allowed on the upper level of this bridge, so the RV, the truck behind the RV (the one with the two guys who are looking in the bathroom window), and the other trucks that are stuck in traffic on this ramp would not, in reality, be allowed there.

Factual error: In the scene where Jack and Algy are eating muffins Jack is wearing a Burberry Check tie. The Burberry Check was not created until the 1920's. The scene takes place in mid-1890s.
