Continuity mistake: When Wesley and Cordelia kiss, after a few seconds they freeze in place. Cordelia has her left arm around his waist, we see a shot of her face for about a second with her arm definitely angled downwards, then we cut to Wes' face and her hand's now on his neck. (00:25:20)
Continuity mistake: As the Trio are discussing their plans near the end of the episode, Jonathan's arms are crossed in closeups and in other positions in wide shots. (00:36:35)
After Life - S6-E3
Continuity mistake: Watch Spike's hand when he punches the wall. The punch lands with his middle knuckle in the wall, but when he looks at his hand it is mostly the largest knuckle that is bleeding. (00:24:55)
The Dark Age - S2-E8
Continuity mistake: At the end of the episode, Buffy complains to Willow and Xander that she will have to blow her allowance on getting the tattoo removed before her Mom sees it. Moments later when Buffy is talking to Giles, the tattoo is gone. (00:40:45 - 00:42:30)
Visible crew/equipment: During the scene of the siege at Giles', there is a shot where an Indian guy jumps through the window and helps himself by holding on to the sill. If you look to the left side of the screen, you can see it's a moving wall and that several hands of crew members are holding it so it doesn't shake.
Plot hole: When Ampata is first released from her imprisonment, why didn't she break the seal then? She knew the only way to re-mummify her was to put the seal back together, so why not shatter it completely instead of leaving it in large fragments? (00:08:40)
Dirty Girls - S7-E18
Revealing mistake: In the opening scene, where Caleb picks up the potential slayer in his truck, there is a brief shot of the two from the hood that pans slightly to the right. In doing so it reveals the edge of a screen showing a fence and trees passing by, revealing that the car is in fact stationary and in a studio. (00:02:40)
Dead Things - S6-E13
Continuity mistake: As Warren is prowling the bar, the tie camera shows a redhead walking past and then a man in a white shirt sitting at the end of the bar in the background. A moment later Warren sees Katrina sitting there. (00:08:20)
Revealing mistake: In the scene where Absalom is speaking of the Anointed one, the line can be seen where the vampire makeup meets up with his real face. This may be seen in various scenes he is in.
Out Of Mind, Out Of Sight - S1-E11
Audio problem: When Cordelia is tied to the chair at the end of the episode from a side view you can see her mouth 'Marcie' but can't hear it and in the front shot she says 'Marcie' again.
Continuity mistake: When the Judge is blown up, Drusilla and Angel leap from the balcony. In mid-air, they somersault and their backs are facing the ground as they fall, but a second later they land on their stomachs.
Visible crew/equipment: In the scene where Buffy is packing Joyce's clothes into a suitcase you can see a mic moving at the top of the shot as they walk through the door.
Once More, With Feeling - S6-E7
Continuity mistake: In the episode 'Once More, With Feeling', when Tara checks out Lethe's Bramble in the book at the Magic Box, she holds the sprig facing to the left in the close-ups, and facing to the right in the long shots. (00:32:30)
The Harsh Light Of Day - S4-E3
Revealing mistake: When Buffy is fighting Spike, she throws him against a table and then runs over it; you can see this is her body double. It is extremely obvious.
Visible crew/equipment: When Harmony sits down opposite the operating table, behind her in the glass there is a reflection of a boom mike.
Life Serial - S6-E5
Revealing mistake: The entire scene where Buffy is experiencing accelerated time, shadows of trees move in the wind but never actually grow or shrink. Even over short increments of time, the sun can move shadows noticeably, and judging from the speed of the people around her, Buffy is in accelerated time for at least half an hour. (00:08:25)
Answer: She has superpowers, ergo fast movement. The reason she outruns him so easily in "Touched" is that she stops trying to actually fight him and just dodges instead.
