When Kate first met Bob (the "Eurotrash in an Armani suit" thief) at the George V Hotel, he spoke perfect English. When she met him again at his apartment when Luc was helping her get her things back, it seemed as if he spoke no English. Luc was used as a translator during the entire scene.
When Kate sits down next to Jean-Paul in Cannes, her left sleeve is scrunched up when she sits down, but between shots of Luc walking away and it cutting back to her, it is pulled down.
The room service doorknob tag on the bed in the hotel room in Cannes.
The length of the telephone wire when Kate calls Charlie.
When Kate finally gets Charlie back and they are in the hotel room fooling around, Kate pulls away from Charlie and her hair in the back is sticking straight up. In subsequent shots, her hair repeatedly switches from messy to perfectly done and back.
Canada has no restrictions on travel to or from the country while awaiting immigration.
When Luc goes to pay for a hotel room with his brother's credit card, the name on the card reads "Mr Antoine Teyssier". Monsieur would be abbreviated simply with an M in French.
The plane somehow manages to land while Luc is in the restroom on the airplane, but he would have been made to return to his seat.
Alternative explanation: Since most of the passengers, at the start of this scene, have disembarked the plane, it is possible that Luc went to the lavatory just after the plane had landed and taxied the runway.

While Luc is driving the stolen Citroen XM he activates the horn by pressing the centre of the steering wheel, but this model of car has the horn button on the end of the indicator stalk.
Kate and Charlie are seen in a car while looking at a house they may purchase; the car has no front plates which all must have in the province of Ontario.
When Kate stops Charlie while they are making out on the bed, he says "Maybe I was afraid of getting married." When Kate responds with "Charlie, You weren't afraid of getting married to her", her lips aren't moving until the last three words of the sentence.
Trains from Paris to Cannes do not go past the Eiffel Tower.
At one point the train is shown traveling away from Cannes and it also shows that it took almost an entire day to get to Cannes. It takes about 5 hours to go from Paris to Cannes by train.
When Luc and Kate are taking of from YYZ (Toronto Pearson airport) on their way to Paris, we see outside the windows vast expanses of farm or forest land just at the end of the runway. There are only mass urban spaces, ie: buildings and major roads at the end of any of the runways at YYZ. Also, while the aircraft is taxing to the runway we see structures at the airport that do not exist at YYZ.
The entire railway route from Paris to Cannes is electrified, but diesel locomotives are shown for part of the trip.
The drive from George V to the Montmatre area of Paris where Bob lives should not go past Trocadero overlooking the Eiffel Tower, or past the Louvre where the glass pyramid is seen.
