Buffy The Vampire Slayer (1997)

Amends - S3-E10

Continuity mistake: During season 7 we are told several times that the First cannot take corporeal form, ie. it cannot touch things. However, in its first appearance in the season 3 episode 'Amends', when it manifests as Jenny Calender and runs its fingers through Angel's hair you can see his hair moving underneath her fingers. It wouldn't be able to do this if it weren't corporeal. (00:15:50)

Factual error: In Amends, season three, one of the movies playing at the theater is 'Abilene,' which was not released until March 13, 1999 ; three months after this episode was aired (and probably five months after it was filmed, which is interesting). (00:43:10)

Amends - S3-E10

Visible crew/equipment: When Willow and Oz realise that it's snowing, the camera pans outwards away from the window. The camera is reflected in it.

Revealing mistake: In the shot with Buffy and Angel on the hill when it first starts snowing, the snow appears much more dense in the middle of the shot, over the characters, than it does on either side, showing where they centred the machine they used.

Other mistake: During this episode near the beginning, Xander says something about Giles not liking Angel to the effect of, "he killed his girlfriend (Jenny) and tortured him." However, the subtitles say "tortured her," not "him."
