Continuity mistake: When the guy walks in on Peter naked in bed, the sheet protecting Peter's modesty is covering him in one frame, and the next moment it has vanished completely.
Continuity mistake: At the end of the scene where Frank chases the car on a bike, he jumps into the car through the driver's window. You can see broken glass flying, but in the very next shot the driver's window is intact again.
Visible crew/equipment: When Alison and Sidney are walking together on the street after a party, they cross the water and the shadow of the cameraman and the camera itself can be seen on the wall behind them and then again on Alison's face.
Plot hole: The FBI in the movie has the ability to "blackhole" an IP address, which makes that computer unavailable to the internet. If they can blackhole the computer acting as the web server, they could also blackhole the computer acting as the name server (DNS), thereby taking down the web site and preventing additional users from connecting.
Continuity mistake: When Lance and Seth Green are riding in the buggy, they are talking for a few minutes. During this time the side shot will show Lance with his arm all the way around Seth's back/shoulder. However, when the camera changed to a full shot, Lance's arms were at his side, nowhere near Seth's back or shoulder. This happened several times during this scene. (00:40:35)
Factual error: In the scene when everyone is in the white Hummer, the vehicle is moving north on the Las Vegas Strip; on the right is Bally's and the Flamingo, with Treasure Island straight ahead in the distance. Yet a few seconds later, when Joy asks the driver to let them out, they are in front of the fountains at Bellagio, which indicates that they are now travelling south on the Strip - yet we never see the Hummer change direction or turn around.
