Continuity mistake: In the scene where Milo Hoffman (Ryan Phillippe) and Lisa Calighan (Rachael Leigh Cook) are working together, and Milo's girlfriend Alice Poulson (Claire Forlani) comes to visit, you see Milo and Lisa stand up - Milo says "Hi". Then Milo introduces Alice and Lisa, and Lisa is sitting down. (00:33:00)
Continuity mistake: When Milo suspects his girlfriend is trying to poison him at dinner he tests his reaction to the food on a cut he makes on his wrist, pulling his sleeve up to the elbow. When she walks back into the room he pulls his sleeve back down to hide it. Then when he makes a toast the sleeve has magically jumped back up again. (01:19:00)
Continuity mistake: When Milo, Alice, Teddy, and the rest of the Skullbox team are at a restaurant (just prior to Milo going on the job interview), there are three closeup shots of Alice. In the first two, a man in a red shirt is to her right, but in the third shot the image is reversed; the man is now on her left.
Continuity mistake: In the daycare building, when the bald guy walks in, he picks up the mouse that Milo left hanging. When he puts the mouse back on the pad it is pointing one way, and when the camera shot changes, it is pointed another way.
Other mistake: In the last scene where all of Gary Winston's crime activities were shown throughout the world, one of his men realized that Milo's girlfriend Alice (Forlani) had lied for Milo. In this scene, when Gary was questioning and threatening Alice about sending her back to jail, try looking carefully and you might be able to see that in one of the scenes Gary's hairstyle had been changed horizontally. Throughout the film he had combed his hair with a parting on the left of his head (right in the audience's view), but in this scene the parting on his hair appeared on the right, left in our view as the audience. It appears only in a few seconds in this shot but it is quite clear after watching the same scene a few times.
Factual error: In the end where Larry and Brian are sitting in the garage, one of them is watching a hit counter for their website, and the other is watching the news stream on the computers. When the reporter is walking up the driveway, she mentions that the site has had 18 million hits.. how did she know this? The SkullBocks server was inside the garage, so the reporters couldn't have checked before hand. And even if there was a counter on the website, they were getting 400 hits per second (1,000,000 hits takes 41 minutes). Assuming they looked at a counter, before the reporters left, it would have been a lot less then 18 million. In addition to this, when they open the garage door up, another reporter asks "How many hits have you guys registered?"
Continuity mistake: When Milo is first in the daycare center and is going through the employee database, and he looks up Lisa's file, there is a picture of her ID card there, but it doesn't have her employee number on it.
Continuity mistake: When Milo is sitting in his car outside the Department of Justice office, a homeless guy comes up and holds a sign up to the window, that says "homeless". In the next shot where the beggar leaves, the sign says "out of work director". A valid mistake, but as an added bit of trivia, the actor playing the homeless man is Peter Howitt, the director of the movie.
Continuity mistake: Throughout the film there are scenes when Milo hits some keys on a keyboard, but the letters appearing on the screen do not correspond to the keys pressed. For example, when he works in the childcare building, there is such line on the screen: "./load nurv/hr_res/tbls/employees.nb" (without quotes). During the time this line appears, we are shown the shot in which he types "pil". But these letters are nowhere to be found in the line. This shot is used at least two times.
Factual error: After the world-wide broadcast has been launched, there are various clips of the incriminating video being shown. One of the clips shows a Handspring Visor PDA (Palm Pilot) showing the video. This would have not been possible because the Handspring Visor PDA was only a black and white screen with no audio other than "clicking" noises. The video sequence was superimposed on the device.
