Continuity mistake: When Tom (Charlie Sheen) is about to pick up the picture, you can see that the person on the right on the picture is on the far right of the frame. When it cuts to a close-up of the picture the person on the right has moved to the middle of the picture. In fact it's basically a different picture. (00:05:25)Mortug

Factual error: At one point, a screencast of a computer screen shows a video of Barry Brickman on the desktop environment of Windows XP (operating system, developed by Microsoft, released in 2001). However, the app that plays the video is QuickTime for Mac (which runs on Mac OS only), not QuickTime for Windows (which runs on Windows XP). These two versions of QuickTime are almost identical in every respect, except for their title bar (the narrow horizontal area above the video). (00:19:15)FleetCommand
