Continuity mistake: When Valentina grabs the wire in front of her neck and cuts her hands, the blood pattern changes between cuts. (There's suddenly less blood in the second shot, revealing it's a different take.)

Continuity mistake: When Gabriella is kidnapped, as Amanda approaches the door of the stall she's in, the way she's holding her purse changes between shots. When it cuts to the angle above, the straps go from over her hands to under her hands.

Visible crew/equipment: When John returns to the clinic to drop off a gift for Gabriele, when the cab pulls up, for a split second, you can see what appears to be the reflection of a crew member (likely part of the camera crew) walking in the green doors right before John opens his door. (It's very hard to see, but you can see it if you pay close attention.)

TedStixon

Audio problem: When John wakes up after the surgery, his lines "Hemoglobin's normal" and "After that, what happens then?" are obviously dubbed in after the fact. His voice is much louder than he appears to be speaking, revealing that they were re-recorded during post-production.

TedStixon

Continuity mistake: When John is fixing Carlos' bike wheel, throughout the scene, it is leaning backwards towards John. However, right before he pulls it out of the vice, it is suddenly leaning forwards towards Carlos. (John never pushed it forward.)

TedStixon

Continuity mistake: When John puts Carlos' bike wheel in the vice, his right hand goes from cranking the vice to holding the side of the wheel as it cuts to Carlos.

TedStixon

Continuity mistake: After Cecilia points out Carlos and his father to John while showing him around, they begin walking again. John goes from walking a few feet behind Cecilia to right next to her between cuts.

TedStixon

Continuity mistake: When John is watching the video of Cecilia, he reaches up and puts his right hand against his face. It then cuts to the opposite angle, and suddenly it's switched to John's left hand being against his face.

TedStixon

Other mistake: When John is watching the video of Cecilia on her website, the video progress bar we've seen twice makes no sense. The first time we see it, it's moving far too fast for the length of the video. Later, we see it a second time, and it has seemingly reset back to the beginning despite it being the same video, and again, it's moving way too fast.

TedStixon

Stupidity: If you pay attention to John's computer desktop, it's hilariously clear that it's just a mockup made for the movie. There are about a dozen files on his desktop that literally just say "File." Every icon has an unrealistically generic name. Etc.

TedStixon

Continuity mistake: When the custodian twists the dial to position two on his trap, his fingers go from extended to curled instantly between cuts.

TedStixon

Continuity mistake: When the custodian grabs the watch out of the drawer at the start of the film, the way he's holding it changes instantly between cuts. (First he's only holding it in his right hand, then he's suddenly holding it with both hands.)

TedStixon

Continuity mistake: When the custodian parks his vacuum near the hospital bed at the start of the film, in the first shot, his vacuum is near the middle of the bed. The camera cuts, and suddenly it's down near the foot of the bed.

TedStixon

Audio problem: When the CT technician asks John if he'd like some help getting down, John says "Thank you very much", but you can tell that he's not saying anything and that the line is just dubbed in. (True, the camera is facing away from him, but his jaw and face aren't moving at all.)

TedStixon

Character mistake: John would have no reason to ask the CT technician if she had any results. He says "that was a long one," indicating he's had this done before and should know it typically takes around 24-48 hours to get results. (Likely just a line of dialogue added for the benefit of the audience, who may not know.)

TedStixon

Trivia: The doctor on the surgery DVD John finds in the ransacked clinic is actually the film's production designer, Anthony Stabley, in a cameo appearance.

Go Fish - S2-E20

Other mistake: After Gage turns into a monster and fights Buffy, the two monsters slide into an open grate. During the shot, there's some sort of weird "glitch" in the background where the garbage can and wall seem to slightly move. All I can assume is that a few frames were trimmed to speed up the shot and it may have exaggerated subtle camera movement, making the background appear to "jump" slightly.

Go Fish - S2-E20

Continuity mistake: When Buffy, Willow, and Cordy are talking at the swim meet (after Gage waves at Buffy), the way Buffy is holding her hands changes back and forth between two positions as it cuts between her and Cordy. Seems two different takes were used, and she had her hands in slightly different positions in them.

Go Fish - S2-E20

Continuity mistake: When Buffy kicks Angelus, suddenly his arm is up in the air instantly between cuts. It seems like two different takes of the kick were used, and in one, he flung his arm up.

TedStixon

Go Fish - S2-E20

Continuity mistake: When Angelus is spitting out Gage's blood, he goes from straight up to leaned over between cuts.
