Factual error: When Arnold is in the police station reporting that he has a clone and passes through a control room, one computer screen is flashing "OVERIDE." The correct spelling is "OVERRIDE." (00:38:05)
Continuity mistake: Towards the end of the movie, in the scenes involving the dying Drucker (Tony Goldwyn) and his half-formed clone, blood on the dying Drucker keeps disappearing and reappearing. In one scene he is bleeding out his mouth and down the front of his throat. The camera cuts away and when it comes back his throat is clean. Yet in the next scene his throat is bloody again. (01:46:10)
Chosen answer: The company did not intend to kill and clone the pilots. The activist killed Drucker and Hank Morgan, they wanted to clone everyone that was killed so nobody would know it happened. The only reason they cloned Arnold was becasue they thought he was the pilot.
