Dodge City (1939)

Revealing mistake: When we see a wagon with a woman and several children in it, the horses get spooked and run. A woman is seen desperately trying to stop the runaway horses. In the next scene you can see the children are not real and the woman is a man dressed in a woman's dress, obviously a stunt man used for that scene.

Rusty Hart: Well, well. So this is Dodge City, huh? Sort of smells like Fort Worth, don't it?
Wade Hatton: Oh, that's not the city you smell. That's you! We better get you to a bathtub before somebody shoots you for a buffalo.

Wade Hatton: Well, what's the news in Dodge?
Charley: Well, just about the same as always. Gamblin', drinkin', and killin'. Mostly killin'.

Jeff Surrett: You see, I make $100,000 a year one way or another. Frankly, I don't need that much money. So naturally, I'd be willing to make a deal with anybody that would, uh, well, sort of see things my way. Make a mighty good deal for both of us.
Wade Hatton: You mean a little friendly bribery, huh?
Jeff Surrett: Well, you can catch more flies with molasses than you can with vinegar.
