Continuity mistake: When Drucker jumps from the roof onto the glass at the end(to avoid the rotors of the Whisper Craft), the establishing shot shows him on the last panel of glass next to the wall. However when you see Drucker fall from the inside shot, he falls from the middle of the glass roof and no wall is seen anywhere near him. (01:51:50)
Continuity mistake: Near the end of the film, Adam and his clone make a jump for the helicopter to escape the explosion. In one scene, you'll see Sport Jacket Adam holding the ladder to the helicopter with Leather Jacket Adam holding onto the legs of the first Adam. After a cutaway scene, you'll see these two have switched places (Leather jacket on ladder, Sport jacket on bottom). The next time you see them, they're switched back in the correct order. (01:52:30)
Continuity mistake: When Talia is first killed, while in the Cadillac, the passenger door is blown off. When Adam drives through the water there's an inside shot of him and you can tell the door is back on for the scene. After going down the stairs there's the same inside the car shot of Adam and you can see the door is missing.
Continuity mistake: In the final shoot out on the roof there is a quick shot of Arnold firing a gun wearing the grey security outfit he stole from the guard earlier in the film. The only problem is at the time one Arnold is wearing his leather flight jacket and the other is still dressed in the sport coat outfit he wore to his daughter's school. This is obviously a shot from an earlier scene they used again later.
Continuity mistake: When a shot of the city is shown from the air (near the beginning of the film), at the top of a building you can see the logo of the Canadian Imperial Bank of Commerce - this is supposed to be set in America.
Continuity mistake: When the Cadillac crashes through the neighbor's fence, it loses the rear driver side hubcap. Later, in a few shots of the tires, the hubcap is back on and then off again.
Other mistake: When Adam lands his chopper on the rooftop, he shows his charter contract as proof he is supposed to be there. There is no information filled out for the dates on the contract.
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.
