Deliberate mistake: Gandu Three Echo, the clone who hits the screen showing the first lottery winner in the movie, complains that he has been around for 7 years and never won the lottery. However, McCord explains later in the movie that the last name tells how old the clones are. Lincoln Six Echo is 3 years old because he is in the Echo generation, and the Delta generation (Jordan Two Delta) is 4 years old. Going backwards, this would make Charlies 5 years old, Bravos 6 years old, and Alphas 7 years old. Gandu Three Echo should have really been Gandu Three Alpha. (00:05:55)
Deliberate mistake: Mr. Medulla said that Will stepped on his foot when he was walking to his desk. If you look closely you can notice that he stepped over his foot instead of on it.
Deliberate mistake: The turn count for Lisa's stay in the Cryogenic Sleep Chamber is off. The card reads she should be there for 5 turns. 'Turn' can either represent a single move made by either Danny or Walter, or a complete game cycle where both Danny and Walter have made a move. If we count the turns by player, it comes to 8 and she's awake 2 turns too late as it should have happened at the start of 6th. If we count both players' moves together as a start of a turn, then she's awake 2 turns too early as its turn 4 and not turn 6. It seems obvious from showing us the shower suddenly start up that this is the correct point in the film they wanted her awake, so it's unlikely she was actually awake off-camera during the Astronaut's arrival and we just didn't see.
Deliberate mistake: On the map showing the location of all the 'Camel Hump' refuelling blimps, none of them are anywhere near the countries EDI visits in the film - the nearest one is more than a thousand miles away over the Pacific.
Deliberate mistake: When Aeon is fastening ropes to lower herself down into the security system, her hair parting has switched sides as she fastens the second rope, revealing a flipped shot. (00:08:25)
Deliberate mistake: When Dead Reckoning is firing the missiles at the end (towards the crowd that's being eaten by zombies), you can tell that they repeat the same shot of the missile firing three separate times, even though it's supposed to be three different missiles. (It's the shot of the exhaust coming out of the back of the launcher.) They try to mask it by cutting a little earlier or later each time... but it's obvious.
