Continuity mistake: Towards the end of the movie when Clark Crashes into Wayne Newton's house you can see the hood of the tour van is not damaged. A few scenes later when they pull up to the casino the hood has a lot more damage to it. (01:15:22)
Visible crew/equipment: At the beginning of the movie when Clark is entering his house and the camera angle is from inside, just as he opens the door there is something red on his front porch. If you look at any of the previous scenes, that red thing isn't there. It's the bottom of a sunscreen being used to block the bright sunlight (which would have flooded the camera) behind Clark as he enters the house. (00:01:44)
Continuity mistake: At the beginning of the movie when Clark is driving home, he skids into his driveway where it is visible that the Ford Expedition is crooked and about three feet from the bike. In the next scene the Expedition is straight and right next to the bike, so that he steps on it when he gets out. (00:01:21)
Continuity mistake: At the beginning of the movie when Clark and his family sit down at the kitchen table to talk about their Vegas Vacation, watch the fruit basket in the middle of the table. It's there when they go to sit down and it's gone in the next scene. Every time it shows the kids it's there and every time it shows Clark and Ellen it's gone. (00:02:32)
Continuity mistake: At the beginning of the movie after Clark trips on the bike, you can see Clark put the Vegas brochure in his jacket pocket. When he goes to open the front door you can see no brochure in his left hand. In the next scene when he enters the house the brochure is back in his left hand along with his briefcase. (00:01:39)
