Factual error: When Reacher talks on the phone with Secret Service agent Molly Beth Gordon, she is using a Huawei phone, which has been banned from all agencies since 2019.
Continuity mistake: A woman approaches Oscar Finlay when he's having a beer at the bar. She asks him "What do you do?" and his hand is at the bottom of the glass, only to be at the top of the glass in the reverse shot. It happens again as the two different angles alternate. (00:36:05)
