Other mistake: Near The Beginning, we see security camera footage from a computer watching Drake type a letter about cancelling the COS project. The footage is too low to be shot by the security camera. It's the regular camera that continues the scene since there is a cut to it from the monitor (and the shot pans to the right before Drake is killed). Many TV shows and movies forget to line up the POV shots from security cameras, using the real footage instead.
Other mistake: It's incomprehensible why such an intelligent COS has to print out the stolen data on Scully’s monitor, risking being exposed. (00:15:40)
