Visible crew/equipment: When the Protagonist passes through Sator's turnstile to return to the ambush site on the highway and gets in the inverted car, a cameraman holding the camera is reflected on the wing mirror. (01:31:38)
Continuity mistake: Angelica has flowers on her dress. During the wedding, they disappear and reappear between shots.
Other mistake: In this film, when they find the picture of Nancy (from the original Craft film), the image is of Nancy in the restroom of the original movie. If you watch the original film, the image that was used of Nancy shown in the new film would have taken place during the scene where Nancy, Bonnie, and Rochelle confront Sarah about wanting out of the coven. But during that scene, no cameras were in sight and nobody was taking pictures.
Continuity mistake: After the first clash with the Witch, as the narration says Hua Jun 'dies', but Mulan lives. The close-up on the blade shows a hand gripping it a couple inches below the blade, while whenever we see her face, before and after that close-up, she is holding it with her finger alongside the guard. (01:03:45)
Continuity mistake: Trevor is driving the Ecto-1 and complains that Podcast is breathing on him. We see Podcast very close to him. The shot cuts and Podcast is now further away.
Continuity mistake: The protagonist receives her gift from Molly Shannon. She unwraps it and puts the discarded wrapping on the counter. When we see it again at the end of the scene, the wrapping is much less torn apart than the first time around (or at least has been arranged neatly). (00:09:45)
