Character mistake: In her first walk through the city with Dr. Ido, after feeding the dog her sandwich, Alita takes a flyer and reads it. Between the lines that read "Wanted" and "Murder" there is a line in Spanish that says "Querido para el asesinato." It should say "Querido por el asesinato".
Character mistake: Queen is an attorney and should know how to conduct herself as a passenger in a car pulled over by police, yet she fails to behave in an acceptable way. Even though certain things may be permissible under certain circumstances, a lawyer should know exceptions and extenuating circumstances, but she apparently does not. She did not have the right to interfere with a police officer and "demand to know" or get out her cell phone to record if she was told to keep her hands where he could see them. (00:10:25)
Character mistake: Reina asked Cory if they could "do that thing" because it was helpful for her medical school training. Reina then put a raw slab of steak/meat across his forehead and made slits in the meat as well as jabbed at it. A medical student studying to become a brain surgeon should know about and practice the safe handling of raw meat. (00:23:10)
