Revealing mistake: Set in Pittsburgh, PA, scenes were obviously filmed out of sequence. Many scenes were "out of sync" with the snowfall, whether in progress or amount (if any) already accumulated. For example, there was no snow downtown, but views from the helicopter showed snow-cover around the nearby parkway (Route 376). In another scene, it was snowing when Ryan turned his Jeep into a downtown road that was covered with at least one inch of snow; switching to a "live" newscast, the sun was shining outside.
Factual error: When Joe and his girlfriend, who is also Albert White's mistress, walk through the hotel room kitchen, that whole kitchen, is not a 30's era kitchen. It even has a convection oven and a blast chiller, pan racks, etc. that are more from this time.
Continuity mistake: At the end, when Gloria hurls Oscar completely out of sight beyond the horizon, a huge crowd of South Koreans rush up directly behind Gloria, cheering and applauding, only a few feet away from her. The camera cuts to a frontal shot of Gloria, and now the crowd is 30 feet or more in the background.
Factual error: When Chiron is speaking with the social worker after being assaulted by Kevin, the social worker urges Chiron to press charges. It is the government who decides to press charges, based on evidence gathered by the police, including witness and victim statements. Crime victims do not decide whether or not to press charges. (01:02:20)
Suggested correction: It should be noted the term "press charges" in this case is meant to denote that a victim of a crime reports the crime to the police (as in file a charge against a person to the police), not the legal sense of pressing charges in court. Plus, victims of crimes can pursue a civil case against a criminal.
Factual error: When Vinny Panzienza has his cervical halo brace removed (without anesthetics), he yells and groans and grunts in pain, but his hands are relaxed on the arms of the chair. I can tell you, from experience with this exact situation, the pain is so intense that his hands should have been clenched as tight as a vise.
Continuity mistake: At the toll booth, Afonso does a thumb up sign to the operator, not knowing what he really said to his son about their ride. He is doing the gesture with his right hand, left hand, right hand again depending on the shot. (00:07:00)
Character mistake: In the newsreel during the growing tensions, a newspaper headline featured with great importance goes like this; "ABUCTED son not yet found." (00:04:30)
Continuity mistake: The bullies spray-paint the lead girl's bike pink, yet in the next scene, it's getting spray-painted again.
Continuity mistake: When Lady Susan is counseling her daughter Frederica in her bedroom, the shot shows an unlit candle on a dresser behind Lady Susan. The shot changes back and forth between Frederica and Lady Susan. When the shot changes back to Lady Susan, the unlit candle is gone, though there is no one else in the room.
Continuity mistake: Maudie lights herself a cigarette. There are 2 matchboxes on the railing of the porch. They disappear for the rest of the scene and Maudie's cardigan and dress do not have pockets. (00:02:35)
Continuity mistake: Mother and son run towards the store window as the Ford Galaxy is burning in the parking lot. At the end of the shot from behind, a woman with a lilac top and long brown hair comes into frame and leans against the vegetable stand. After the cut, with Jamie and the mom by the window, the same woman walks in again. (00:01:30)
