When Darcy leaves the apartment, Max is in the main room. In the next shot, he's in the Kitchen doorway.
Max's car gets splashed with toxic waste. It's clean/dirty on and off for the entire scene.
At the beginning of the film in the Air Traffic Control Tower, the wall clock in the background changes time between shots.
As Max drives away from the airport, he stops very close to a chicken truck. In the next shot he is quite a way behind it.
When Max is stopped behind the Chicken truck a feather lands on his eye which switches eyes between shots.
After Max levitates the bar of soap, the soap lands in the sink. In the close-up, two holes for the string can be seen.
When the airplane-ashtray flies, a large, obvious, metal arm is supporting it in the close shots.
When Mark (and later Mark and Darcy) are on the beach, the camera tracks can be seen in the foreground.
When Max tells Lorraine that Darcy is also at the club, she responds "shoot," but her mouth is clearly saying a more explicit, four-letter word.
