Factual error: In the scene where Lewis dials the police at the gas station, he says "Rawlins County Sheriff's Department please." There is no such county in Wyoming (where this particular scene is) named Rawlins County. He should have said Carbon County. Also, Table Rock is in Sweetwater County, and there are no police services there. (00:36:50)
Continuity mistake: When in the hotel room waiting for Rusty to arrive and knock on the angry man's room, Lewis is on the phone with the front desk. The phone is on the nightstand facing him. The scene shifts to Fuller, but when the camera shifts back to Lewis again, the phone is turned to face the other bed. (00:41:00)
Plot hole: The incident at the hotel happens in the town of Table Rock, Wyoming. Aside from Table Rock not having any hotel, the drive from Table Rock to Boulder, Colorado is only 4 1/2 hours. Unless they're crawling, why is this trip taking two days? The film uses real life locations and town names. The rest of the film is justifiable as Rusty controls the game, but the first act of the film's timeline is messy.
