Buffy The Vampire Slayer (1997) - 404 mistakes in entire show

Factual error: During Buffy's training montage, she is seen punching a bag with her wrists bent. First, that's going to be a weak punch, super strength or no, because she can't transfer the force from her arm and body; it just bends at the joint. Second, that's a great way to injure your wrist, because all that escaping force snaps the bend farther. You could strain or even break the joint. After six years, Buffy should know better.

Continuity: In the musical episode, 'Once More, With Feeling', when Buffy is singing her song in the Bronze, 'Something to Sing About', she breaks a pool cue over a demon's head. She holds the remains in her right hand and clubs another demon in the face with it, then the camera cuts to another angle and it's in her left hand when she stabs the next demon with it.

Continuity: During the final song, everyone, including Spike, sings "When Does the End Appear?", however, one shot later, Spike is seen starting to sing the word "appear" again and then he stops.

Continuity: 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.

Revealing: When Sweet's henchman shows up at the Magic Box to tell Buffy that Dawn is being held hostage you can see the actor's real mouth moving inside the mouth of his costume.

Audio problem: In the episode 'Once More, With Feeling', when Anya sings her first few lines of the song 'I'll Never Tell', you can still hear Xander talking about omelettes in the background, but for the last few lines he speaks (from 'I could do an omelette' onwards) you can see over her shoulder that his voice is dubbed.

Revealing: The knives Giles throws during Buffy's training are a very poor CGI job if you watch it in slow mo. All three knives Giles takes off the wall are identical, with a broad curved blade and a plain black handle. The first one has a transparent blade as it flies toward Buffy, then we hear it bounce off the far wall and it's way out of scale for the distance. The second knife has a diamond-patterned grip instead of a plain one. The third knife conveniently spins in midair for a second so Buffy can kick it out of the way.

Continuity: When Buffy and Dawn are discussing Buffy's new name choice Dawn's hair changes repeatedly between shots. First it's over her shoulders, then behind, she has a clip in one shot, then she doesn't.

Continuity: In 'Tabula Rasa' when the loan shark's henchmen throw a stake at Spike at the start it flies over his head and hits a tree. But, if you compare the angle they approach from with the relative positions of Spike and the tree you can see it would have had to do a 90 degree turn in mid air to fly over his head before hitting the tree.

Continuity: In the beginning of the show, Buffy has two necklaces on, one long and one short. However, when Buffy, as Joan, is telling everyone her plan to get away from the vampires, she only has the short necklace on. Then when she is outside, running from Spike, as Randy, both necklaces are back on.

Continuity: When Anya is standing on the table, wide shots show her holding the spellbook in front of her, but closeups show her holding it tight to her chest.

Continuity: When the Trio are conferring about helping Spike, from the front Warren's arm is on Jonathan's shoulder, but from behind both his arms are at his sides.

Audio problem: When Warren, Jonathan and Andrew break into the museum to get the diamond, Warren makes a hole in the glass, then pushes it through, but when it lands, it sounds like plastic, not glass.

Other: The newspaper that Xander is reading in the library has the same text over and over again and does not at all match the headlines.

Continuity: The episode begins the morning after Buffy and Spike first have sex. That night, Willow and Amy go out again to find Rack's place, and this cuts directly to Willow waking up the next morning. But later in the episode, Spike makes repeated references to what happened between him and Buffy "last night", when in fact it was two nights ago.

Revealing: After the demon throws Buffy into a wall, she crashes to the ground. As she backs away, you can see the blue crash mat she landed on in the bottom left of the screen.

Continuity: Just before Buffy storms out on Spike, she puts on her denim jacket. When viewed from in front we can see the jacket is only half over her shoulders and her hair is loose. The shot cuts to view her from behind, and the jacket is now completely on and her hair is tucked under the collar.

Continuity: When Buffy and Willow have just returned from a night out and everyone is in the kitchen, Dawn's hair keeps changing from being over her shoulders to behind, to over one shoulder in different shots.

Visible crew/equipment: Just after Dawn says "I like the trailers", we fade to black/commercials, then up again. Keep a close eye on the left side of the screen - you can see what looks like someone's hand flash into frame for a second, despite Dawn being alone in the room - looks like the director's hand signalling action.

Revealing: Spike is supposedly naked in the building when he and Buffy awaken, but several times during the scene when he's asking her to stay, you can see the skin-tight, skin-coloured underpants he's wearing.
