Corrected entry: Right at the end of the movie, when Jim is dancing to Nadia we can see Jim's father appearing behind him, but a few seconds later there is an outside shot of the room where his hand is lying on the door frame.
Corrected entry: During the Lacrosse game when you see Oz score the goal, there is an illegal hit, Oz has the ball and a player from his team hits another player on the opposite team, that is an illegal hit and the goal would not count.
Corrected entry: When Nadia is in the bedroom, and Jim is using the camera to webcast her, the angle we see on his friend's computer is totally different to that on another computer we are shown.
Corrected entry: In the beginning, Oz is in the car with the college girl, he tries to 'seduce' her, then she says: 'That's pathetic'. Her mouth is not moving at all.
Corrected entry: When Jim is 'experimenting' with the pie, his dad walks in and immediately exclaims in horror. However, Jim is standing with his back to the door, with nothing visibly amiss.
Corrected entry: When Jim's setting up his computer to take a photo of himself for the dating site, we see shots of him trying to look good for the camera. However, in the supposedly live shots of him gurning at the camera on the monitor the blinds are open, whereas in the wider shots of him in the room they're well and truly shut - the webcam footage was obviously taped.
Corrected entry: When Jim is setting up his computer camera and adjusting and re-adjusting it so it centers around the bed area, his dad brings Nadia in the room and Jim excitedly jumps up and bumps the desk. You can see the camera on top of the computer move substantially out of position. There is no way anyone would have seen anything but the wall.
Corrected entry: In the final lacrosse game when Oz scores, it looks like when he shoots, it doesn't actually go in the net, but hits the bar instead.
Corrected entry: When Jim's friends are watching him dancing for Nadia on the webcam, they can hear the dancing music Nadia has playing, which is strange, because Jim hasn't set up a microphone.
Corrected entry: The first time Nadia is mentioned, she is referred to as a Czechosolvakian exchange student. Later in the movie, when Kevin and Finch are waiting for Jim in Kevin's room (to see Nadia on the Net), there is a sticker on the mirror that says Class of 1999. The problem is, Czechoslovakia didn't exist in 1999. It split into the Czech Republic and Slovakia in 1993.
