Factual error: The Sheriff's car had "POLICE" written across the rear end, but with the exception of Allegheny County, deputies in Pennsylvania do not have police powers. They are County employees who carry out court orders (e.g, serving warrants and subpoenas) and work in court houses keeping order. They also transport prisoners and issue gun permits. It would be atypical for a Deputy sheriff to do routine patrol like Deputy Myers was doing. The sheriff's car should have had "municipal" or government plates. (01:16:18)
Factual error: The Deputy's identification had "State of Pennsylvania" written on it. Pennsylvania is, of course, a state, but most (if not all) official/ legal documents are marked "Commonwealth of Pennsylvania." (01:17:05)
Continuity mistake: When the Virtuoso returns to his car parked behind the stable, it is once again not how he parked it. The passenger side is no longer aligned with the inner side of the white support beam - it extends slightly beyond the outer side of the beam, and the passenger side mirror is entirely outside of the beam's edge. (01:18:21)
Factual error: Waiting in his car to see if the "impostor" sheriff will leave the farmhouse, the Virtuoso looks into the passenger side mirror and is able to see the truck, car, and sheriff's car parked alongside the front porch. Even if the mirror were turned out as far as possible, it would not be able to capture the vehicles as shown. At most, the other part of the house and/or the side of the stable would be visible using the mirror. (01:18:22 - 01:19:04)
Plot hole: After the Sheriff crashed into a tree, the Virtuoso passed him up but returned. The Virtuoso asked the Sheriff if he knew "White Rivers" and the Sheriff responded, "Yeah, I know it." The Virtuoso then shot at the Sheriff who was a few feet away and hit him in the neck. The Sheriff was able to run away. Instead of the Virtuoso quickly shooting again, he watched the Sheriff run into the woods and chased him. Despite being "experts", each made numerous shots that missed the other. (01:21:37 - 01:23:29)
Other mistake: The waitress said she got to Rosie's Cafe early and had to kill Rosie and the cook. She shot them and threw them down the basement steps, plus mopped up the blood before the loner arrived. The Virtuoso did not get there as early as he wanted to, but it was still about before 5:00 PM. He had briefly stopped along the road to ask the girl if she wanted a ride, and the waitress passed him at this point. The small amount of time the waitress was ahead wouldn't be enough time to kill and clean up. (01:35:30)
Continuity mistake: The Mentor slid a folded piece of paper across the desk to the Waitress; the crease was to her left. When the Waitress picked up the paper, the crease was facing her and the note opened toward the Mentor. (01:38:31)
Other mistake: The Virtuoso kept a large bag (50#?) of dog food outside near the front door of his cabin. The Waitress put another bag beside the first one. Especially in the woods, food should not be stored outside - wild animals would quickly smell and devour it (if mice/rats did not get to it first).
