The British casino had an American roulette wheel with two zeros instead of a British wheel with one zero.
While in London, Jonathan calls Jennifer "the queen of Beverly Hills". In fact their house is way too small to even qualify as a mansion, and seems to be one of those modest houses off a side street, well away from the multi-million dollar Beverly Hills mansions. A far cry from a dwelling fit for a queen, let alone of wealthy Beverly Hills.
As Jonathan is headed to the hotel, he gets pulled over by a motorcycle cop. Instead of giving the officer the legitimate reason for his speeding, he says that Jennifer is in labor, even though she's visibly not pregnant. The officer could have easily verified why they were in a rush since LAPD was already looking for the inspector.
