Other mistake: The steamship shown in Patriot games is actually a shot from John Wayne's 1955 Sea Chase.
Suggested correction: The use of stock footage in movies is a common practice. More context would be needed to explain why this is a mistake.
Factual error: Just before Sean Miller shoots the bookseller he takes the safety catch off the Ak-47. However, he moves the catch two clicks down and then fires the weapon on automatic. This is incorrect. For most modern weapons the safety catch feature goes safe-semi-auto, however the AK safety catch goes safe-auto-semi.
Suggested correction: I watched this scene twice to verify - there is only one click.
Other mistake: When in court as Harrison Ford is leaving after his testimony, Sean Bean puts his right hand behind his back a couple of seconds before the "officer" grabs it. (00:24:27)
Suggested correction: This is a mistake only if you believe Miller's intention during this scene was to grab or strike Ryan. If Miller merely wanted to rail at Ryan, it's understandable that he'd put his arms behind his back preemptively in order to avoid excessively rough treatment from the bailiffs.
