Continuity mistake: Early on when Rusty is teaching the actors to play poker, there's a scene when Rusty says "Shane, you've got three pairs...you can't have three pairs. You can't have six cards in a five card game." Look at Topher's (the man who wanted to pay Rusty by check) cards during this scene. At first, he's holding the cards up, then flat on the table, then back up again. (00:07:00)
Continuity mistake: Danny's hairstyle changes dramatically in some scenes in the movie. Most notably when he and Rusty are in the office building looking at the blueprints of the hotel vault. It looks like he just got a haircut. In the previous scene and next scene his hair looks longer and styled different. (00:12:15)
Continuity mistake: Towards the end of the film, there's a scene where Tess runs into Terry as she's getting off the elevator to go find Danny - Her hair is smooth and styled into a French twist. As she's walking down the steps into the casino, Terry calls after her and she turns to face him - This time, her hair is wavy and in a different style.
Continuity mistake: In the scene where Tess is stepping out of the elevator and she runs into Terry, her hair is in a sleek, perfectly-styled French twist. Then in the next shot when she turns to him and says, "You of all people should know, Terry, that in your hotels, there's always someone watching." Her hair looks messy and disheveled.
