Continuity mistake: In the scene where Wyatt and Gary are taking Deb and Hilly home in the Ferrari and Porsche, Gary is being pursued by the police. When Gary approaches the railroad tracks, the train is shown coming in the direction of the passenger side door. When they finally cross over the tracks, the shot is flipped, and the train is seen to have crossed the intersection in the direction of the driver's side door.
Continuity mistake: When Gary grabs the FDX system unit (Memotech), the monitor (with green text) which sits atop the system unit falls backwards, and he then throws the system unit out the window. However, the FDX unit is back on the desk, with the monitor atop it (they are between the display monitor and feed scanner), when the boys are on the floor.

Continuity mistake: Lisa has just exited the shopping mall. Gary pulls up in the Porsche. When Gary pulls up onto the curb, the cars behind the Porsche include A white coupe, a blue sedan, a silver Chevy Monza and a brown Lincoln Town Car. Gary gets out of the Porsche and says " Lis' we're running late" and the cars have completely changed except the silver Chevy Monza. Lisa turns to get into the Porsche and the cars behind them have completely changed yet again. Now they include a Brown Van and a silver 4 door Plymouth Horizon. Obviously the mall parking lot was not closed during filming, and this 2 minute scene was shot over the course of several hours.
Continuity mistake: In the gym, when Ian and Max walk up behind Gary and Wyatt, there is a closeup of their feet, and we see that the left laces on Gary's high tops are laced all the way up, tied snugly. However, when Ian and Max pull down the boys' shorts, in this close-up Gary's laces are only midway up the high top's eyelets, loose and untied.
Continuity mistake: After the party, when Chet gets out of the vehicle, he has five shotgun shells in the front of his vest. As he walks up the stairs, he has three shotgun shells in his vest. A few seconds he opens his bedroom door and he has five shotgun shells in his vest again.
