Deliberate mistake: Michael B. Jordan has a small indentation on his forehead, just above his right eyebrow. By virtue of the fact that he plays twins in this film, both characters have the exact same indentation.

Continuity mistake: The green Alfa in the opening minutes has its side, and mirror, wiped out by a lorry. For the next 5 minutes it then drives around in perfect condition. (00:05:43)

Continuity mistake: The Saturn that Mikaela is driving has a moonroof that encompasses most of the roof, over the front and back seats. When the Decepticon Grindor captures them, in the interior shot looking up at Leo as Grindor seizes the Saturn, the car has a solid roof over Leo, which is also seen in the interior shot as they fall. (00:54:05 - 00:55:05)

Plot hole: Reed's plan to teleport the planet away is based on the upscaling of the teleportation device he invented a couple of days prior. Every time he uses it, though, it uses TWO pads: a transmitter and a receiver. It takes the collaboration (and the power grid) of the whole planet to use the transmitter, but the receiver is conveniently absent. It would have invalidated the whole plan.

Continuity mistake: When Mrs. Otterton is in Chief Bogo's office holding her family photo with both paws, in the wideshots her purse is hanging in the crook of her left arm, but after a brief shot of Judy, when it cuts to Mrs. Otterton's closeup as she tells Bogo about her two beautiful children her purse is gone, then after another brief shot of Judy the purse is back in its place again in the wideshot.

Trivia: When composer Éric Serra showed Inva Mula, the Albanian soprano who was going to sing the Diva Dance, the sheet music for that part, apparently she laughed and said that it was impossible for the human voice to switch from high to low notes that quickly. She got her way: The part that ended up in the film is not a single piece of audio, rather it's several pieces stitched meticulously together.

Continuity mistake: After S.H.I.E.L.D "borrows" Jane's research and Darcy says that they took her iPod, her hair can be seen blowing in the wind in the shots facing her left and not blowing in the shots facing her right.

Question: I probably missed this, but why does Dina keep saying, "muskrat" to Jack?

Alita: I do not stand by in the presence of evil.

Continuity mistake: When Rey enters the Emperor's vault on the Death Star she is wearing her satchel, slung across her body. When she falls out backwards after seeing Dark Rey she is still wearing it, when she stands to confront Ren, it's gone.

Other mistake: Towards the beginning of the film, the teacher counts 19 students then says one is missing, implying there are 20 (including Mike) However, Mike ends up being paired with the teacher, despite there being an even number of students and therefore everyone should have a partner.
