Continuity mistake: In the scene where Eastwood is watching "the city of Lago volunteers" training,he is drinking a beer. The first time he lifts the glass to drink, it is about half empty. After he says something to the man with the knife, he lifts the glass for another drink and it is nearly full.
Factual error: When Clint Eastwood first goes to the barber shop, the barber very deliberately sharpens his razor the wrong way, flipping the blade with its sharp edge against the strop - this would instantly dull the blade. No real barber would make this mistake, but it's a common movie error.Charles Austin Miller
