However, when Cole takes the phone from Terry, he does not take Rosa off of hold and proceeds to talk to him. 134637 During the scene in which Ben is introduced to the card-counting group, several members are sitting at a blackjack table. There are cards on the table in front of them. In the first shot, the cards are face up, in the next, they are face down, then they appear face up again. While no one is seen or heard dealing cards, the number of cards on the table changes in several shots. 137118 In the very beginning of the movie, Ben is seen riding his bike over the bridge in an aerial shot. Near the top of the screen, if you look carefully at the end of the bridge you can see a police barricade at the end of the bridge. It is there because the bridge is closed for filming. 134723 In the scene at the beginning of the film where Ben, his mother, Josh, and Cam are celebrating his 21st birthday in the bar with the cake, Ben's mother hands Josh (sitting on Ben's right) a slice of cake and he says "Thanks." In one of the immediately following shots, Ben's mother is yet again giving Josh another piece of cake. Surely he can't have eaten it all in 3 seconds. 134669 Jill tells Ben that she has a suite at the Hard Rock and asks if he would like to see it. In the next scene it shows her looking out the window (presumably at the Hard Rock) and seeing the fountains of the Bellagio. This is not possible as these two resorts are almost two miles apart on different roads.
