Revealing mistake: As the flat bed trailer hits the Winnebago, the stands holding the motor home stable are visible.
Continuity mistake: When Cade and Lucas are walking up to the theatre, in the shot where they are approaching the owner, he is shown leaning against his car and facing away from them. The shot then cuts to the owner, where he is suddenly facing towards them. (00:04:50)
Continuity mistake: When Tessa and Lucas are telling Cade they need to get the truck out of the barn, Cade says he's been working in there all night, and he is fine. His arms are raised when he says this, but when the shot cuts, his arms are suddenly by his side. (00:26:05)
Continuity mistake: As Shane is driving to escape the Black Ops cars, he drives through a chain link fence with a private property sign on it. A second later, he hits it again.
Chosen answer: The battle that lead the government to hunting all transformers was in Chicago, but the incident that took Optimus out of commission was not. He'd been on the run for however long, even changing his appearance to avoid detection, when he was ambushed. Wounded, he snuck into the theater to hide before transforming one last time into vehicle form at which point he basically passed out, lost consciousness, or whatever it is robots call it when they involuntarily shut down (stasis). His aggressive reaction upon waking is simply down to his instinctive warrior reflexes immediately kicking in. All humans are a potential threat to him now, so he reacted accordingly in an instant.
