Corrected entry: The harmonica that Harmonica puts in Frank's mouth, after the shootout, is of a different type than the one Frank had put in the mouth of Harmonica as a kid in the flashback.
Corrected entry: We find out pretty quickly into the movie that Frank has no idea who Harmonica is, or what he wants. So, why would Frank send three people to meet him after he gets off the train?
Correction: Frank doesn't know who he is, but he thinks (correctly) that he's dangerous.
Corrected entry: When in the opening scene at the station the train starts moving Frank's men hear Harmonica's tune. He appears behind the leaving train, but in the wide shots he has both hands down while he is heard playing. Only in close-up he is holding the harmonica to his mouth. (00:10:50)
Correction: This is incorrect. Throughout the whole scene, Harmonica has one hand holding his bag and the other holding the harmonica. At no time does he have both hands down.
Corrected entry: Why didn't Frank's men attempt to outbid Harmonica when he successfully made the $5,000 bid (using Cheyenne) for the railroad station? It's not like they didn't have the money, given that Frank tried to buy the property back off Harmonica later.
Correction: I suspect that they would've outbid him, if they had the right amount of money. That property would've gone for five hundred dollars if Harmonica hadn't walked in at the last moment. Harmonica was feeling the bid process to see how much money Frank gave them. Let's face it, if you gave those band of cutthroats an exorbitant amount of money, you would probably have to hunt them down and kill them later. Additionally, back in those days, I am sure they wanted cash on the barrel head after you won a bid in an auction. (Or proof of property that is worth that dollar amount.) I mean you couldn't just whip out a VISA card and charge it.
Corrected entry: During Cheyenne's nightly visit at the McBain farm Jill jams the coffee kettle on the table where Cheyenne is sitting. Then there is a cut to Morton and Frank in the train, where they discuss the issue with the late McBain's farm and widow at broad daylight. Then it cuts back to Cheyenne still sitting at the table, sipping coffee, continuing his conversation with a now more cheerful Jill, and it's night again. (01:08:45)
Correction: Cheyenne is paying a morning visit to Jill. Some time during his 'speech' he says "Didn't sleep a wink all night" That scene begins with Jill carefully looking out the window - it is broad daylight and the roosters are crowing.
Corrected entry: When Maureen came out of the house she was humming the song "Danny Boy" That song wasn't written until 1913.
Correction: "Danny Boy" was written in 1910. In 1913 the song was set to the tune of "Londonderry Air." Maureen was humming "Londonderry Air", which was published in 1855.
Correction: There's nothing requiring it to be the same harmonica. It's the gesture of putting a harmonica in his mouth that's significant and that makes him remember, not the harmonica itself.
