Buffy The Vampire Slayer (1997) - 77 mistakes in series 2

Factual error: In the episode 'I Only Have Eyes For You', during the flashbacks to 1955 James and Grace dance, and James later shoots himself, to the song 'I Only Have Eyes For You', which wasn't released until 1959.

Continuity: Willow is turned into a ghost. Throughout the entire episode, she can't touch anything (can't turn the pages of a book, etc.), yet towards the end when she and Giles go to Ethan's shop, and she leaves, you can hear that she opened and closed the door, even though she can walk through walls and can't actually touch the door. The curtain moves when she leaves too.

Continuity: Joyce is driving Buffy to school and she is wearing a pink tank top. At school that day her shirt is white, but the next day at school she is back to wearing the pink outfit.

Audio problem: When Xander, Willow and Umpada meet up at The Bronze, the song the band is playing is at the point of a guitar solo. If you watch Oz (who has already been established as 'lead guitarist') on stage in the background; he's blatantly NOT playing that solo. The hand movements don't match up.

Continuity: If Spike and his gang only take a few hours to break through the door to Ford's club in 'Lie To Me' (which we are told is six feet of solid steel), why can't Angel break through a thin wire door that visibly shakes every time he hits it, given the same amount of time, in the episode 'What's My Line? Part 1'?

Continuity: When Willow is running from the werewolf she falls and there's a big mud stain on her pants. In the next scene when she runs into the library it's gone.

Continuity: When Buffy is fighting Kendra the fragments of the table she is thrown onto have disappeared when she stands up again.

Continuity: While studying at the Bronze, Buffy and Willow leave their books on the table to go and dance. Spike calls them outside to fight a vampire, and when Xander runs back inside to grab a stake the books have all been put back into Buffy's bag.

Continuity: The book that Cordelia replaced sideways in the bookshelf behind her disappears, and then reappears just before she and Xander kiss.

Continuity: When Buffy looks into the childrens' ward the sign on the door saying 'Basement Access' disappears and reappears between shots.

Continuity: When Willow is escaping from Oz the werewolf she runs into the library, where Giles is. In the first shot, he isn't wearing his glasses, then in the next shot he is, then he isn't, then again in the next shot he is.

Deliberate "mistake": After Jenny pushes the janitor's cart into Angelus and runs up the stairs, there's no physical way he could be waiting for her at the top of the stairs (even with vampiric speed). Joss Whedon has admitted in interviews that he put in this blatant continuity error as the situation is a staple of the horror genre (girl runs from villain, only to find him standing right in front of her).

Continuity: When the Anointed One is killed by Spike, he disintegrates into dust. But in the overhead shot, there is no dust on the floor, even though it should have fallen through the bottom bars of the cage.

Continuity: The vampire Angel fights in Buffy's house was never invited in.

Audio problem: When Jenny and Giles are talking and Jenny is talking about the festival, they walk behind a drinks machine and then her lips don't match up with what she says.

Continuity: Drusilla kills Kendra by cutting open her jugular artery and leaving her to bleed to death. When Buffy enters a while later, there is not a drop of blood anywhere.

Continuity: Near the beginning when Buffy and Willow are talking about Willow getting together with Oz, Buffy's hair is in front of her ears. Then she turns to face Willow to say, "You think he's too old 'cause he's a senior? My boyfriend had a bicentennial," and in that shot change, her hair switches to behind her ear then goes back to being in front of her ears in the next shot without her every touching her hair.

Plot hole: In the flashback to Buffy in L.A., how did Angel get there with the front windshield of his car blacked out? Being a vampire, he obviously needs it during the day, but he also wouldn't be able to see traffic. And it just seems to be too much of hassle for him to remove it at sunset, just to reapply it at sunrise, just to remove it again, etc.

Audio problem: When Giles and Miss Calender are walking through the halls at the beginning of the episode there's a kid at the vending machine, we hear the coins rattling but he never puts money into the slot. In fact, the money doesn't go anywhere near the slot.

Audio problem: When Giles looks through the window of a door at the high school and sees the janitor yelling at the teacher, the janitor's lips don't match with what he is yelling.
