Continuity mistake: Just before Skinner shoots Alex Krycek in the head, Alex is lying weakly on the ground, having already been shot twice. However, as Skinner makes the kill shot, Alex is suddenly standing and falls to the ground upon impact of the bullet, with no time (or strength) for him to have risen. Also, the last shot of the dead Alex shows his face and his nostrils flare from breathing.
Three Words - S8-E16
Continuity mistake: When Mulder sits at the computer terminal in the census records room, we see two empty boxes on the screen, one for an ID and one for a password. The shot cuts to Mulder, then back to the screen and shows him typing the password, while the ID has already been typed in; it is very long and there wasn't time in between shots or nearly enough clicks of keys for Mulder to have entered that ID.
Continuity mistake: After Rob returns to his apartment after throwing out the trash bag with the bloody shirt inside, his mouth starts bleeding and he goes to the bathroom. He removes his false teeth and a few of his real teeth start falling out; he has a small smear of blood on his bottom lip when the camera is looking at him but his mouth is clean when the shot changes to his reflection in the mirror, with no time in between for him to wipe it.
The Post-Modern Prometheus - S5-E5
Continuity mistake: Izzy unwraps a peanut butter sandwich and sets it on a bare tree stump as bait for 'the Great Mutato', then he steps away with the others. When we see the Great Mutato hurriedly put it down, a paper bag is suddenly sitting on the stump beside the bitten sandwich.
Continuity mistake: When the prostitute, Holly MacClaine, is first murdered, we see her face up. The next morning, when the police are at the crime scene, we see her face down.
Continuity mistake: Pusher loads the revolver with one bullet, leaving five chambers empty. When Mulder picks it up and points it at Pusher, the bullet can be seen in the cylinder, just to the right of the gun barrel. Later, when Mulder begins to slowly pull the trigger for the third time (aiming at Scully), we see the cylinder turn to Mulder's left. Problem is, with the bullet situated as it was when Mulder picked it up, the bullet would have moved to the barrel and been fired the first time he pulled the trigger, killing Pusher. Instead, it fires on the third pull.
Continuity mistake: When Mulder breaks into the boat, the door shuts, but in the next shot it's wide open. Shot after that, it's closed again.
