Revealing mistake: Nick's reflection is seen in the shiny ceiling, but the guns floating above him have none, revealing this to be a CG effect. (00:54:50)
Continuity mistake: Kira, the men under Kira's pushing power and Agent Henry Carver are standing on the roof top. Carver told Kira that they were on the same side and he wanted her to march the men that were shooting at them off of the roof. Nick races to the roof top and Carver beats him and pushes him to jump off of the roof top. Nick turns around and punches Carver and steals the syringe. The men pushed by Kira move behind Kira while Nick tries to get her attention. Nick injects himself and collapses on the floor. Agent Henry Carver says "What a waste" and walks away with Kira. The men that were under Kira's mind control disappeared from behind her. (01:41:05 - 01:43:05)
Suggested correction: The two men behind her fall through the hole in the floor after Carver tells her to march them off the building. The movie shows them fall, leaving only the two men on the other side of her.
Other mistake: In the end credits, BASSES is misspelled as BASESS. (01:45:10)
Audio problem: At the end of the movie, when Cassie says, "This case is the key to bringing down Division", her mouth doesn't move at all.
Character mistake: When Agent Carver is convincing Kira she's an agent and volunteered for the experiment, her badge reads Kira Hollis, but the end credits her name is Kira Houston.
Other mistake: In the DVD bonus feature "Science Behind the Fiction", director Paul McGuigan describes says he typed "psychic powers experiments" into a search engine. This is illustrated with a computer display on which the text being typed reads "pychic powers experiments."
