Continuity mistake: Grewishka makes his grand entrance inside the bar: as a poor schmuck asks "What's happened to him?", a guy in the background is sitting, but in the shot immediately after, he's standing and only after a moment he slowly sits down. (01:01:30)
Continuity mistake: As Alita punches Zapan and dispossesses him of his weapon, the large sword, in a rather unbelievable bit of CGI, flies off the side between two patrons at the table. Unless we assume a pinball-like bouncing trajectory, you can't explain how it ends up being back directly in front of Alita for her cool kick toss a moment after. (01:00:20)
Continuity mistake: When Alita, enraged by Ido's refusal to connect her with the body, smashes the metal cart, in the shot from above various vials and a roll of bandage are tilted and tipped, but in the side view the vials do not appear and the roll is still perfectly vertical. (00:53:50)
Continuity mistake: Alita sends Zapan face-first into a wood table when he grabs her by the throat. When the section of the table breaks, a bowl with snacks is still on it. When Zapan reacts, the bowl is gone. (01:00:05)
Continuity mistake: The freshly rebuilt Alita enters stage right with a jump by Hugo. Landing, there's a person walking across the archway who disappears when Alita is standing up from the crouching position. (01:13:50)
Continuity mistake: When Alita decks Tanji, he faceflops past a manhole. In the reaction shot that follows, Tanji is suddenly by the manhole, and the lighting of the scene is totally different from before. (00:19:45)
Continuity mistake: At their first encounter, Hugo asks "Did Doc Ido do it?" checking out an upturned hand, which becomes downturned right at the cut. (00:12:03)
Continuity mistake: In the unfortunate outcome of the encounter with Zapan in the alley, Tanji lies on the floor in two completely different ways. (01:27:20)
Continuity mistake: The position of Alita's hands on Hugo's face changes between shots a few times as she holds him in the church. (01:38:55 - 01:39:40)
Continuity mistake: The hair on the severed head under Alita's arm changes arrangement between shots. (01:41:00)
Continuity mistake: In the battle with Grewishka and the other two murderous cyborgs, Ido loses his scythe that falls down with the sharp edge pointed towards his right. When Nyssiana disrobes, though, the scythe is turned the other way incorrectly, with the pointy end on the opposite side and the burner on the right. (00:28:15 - 00:29:00)
Continuity mistake: After Alita slides away from the Centurion, dog in hand, she freezes in the pose at the side of the road. To her left, witnessing the scene there's a woman wearing sandals and some rasta patterned pants. She is standing by the corner of the sidewalk, but when we see her after a brief reaction shot on Hugo, she is standing super close, literally in Alita's shadow (they both shifted away from the corner, technically). (00:11:15)
Continuity mistake: During the whole sequence when Alita wakes up in bed, in the closer shots the blanket directly by her pelvis is on top of the mattress, while in the shots from a wider angle part of the blanket dangles off the side. (00:04:00)
Continuity mistake: Alita just woke up at the beginning of the movie. When she sneaks downstairs checking out of the unfamiliar location, she suddenly has her hand on the railing between shots. (00:05:30)
