Factual error: At the beginning of movie in the van scene, when Will's daughter calls, he is using a Blackberry 9700 series (if the heist is set 8 years in the past this phone did not exist). (00:04:30)
Factual error: Before Harland arrests Will, he gets out of the cop car with a block of cash. Later in the movie you learn he burned it. There was a burn barrel next to the car with a low fire in it as he gets out of the car. It cuts to the cops yelling at him with a mega phone and then back to Will walking away from the barrel. Now the fire is roaring high up. It grew much too fast and high for such a short time. Money is not that flammable. (00:19:40)
