Support Your Local Sheriff (1969)

Revealing mistake: When McCullough is discussing Prudy's oddities with the matronly lady out front of the mayor's house, it is obvious that the lady is standing on a dirt-covered concrete sidewalk.

Continuity mistake: The Danbys ride in with 13 gunmen. Prudy kills two. Both are shown lying dead in the middle of the street. A few minutes later both dead Danbys are missing from the street and there are once again 13 live Danbys facing Joe stretched over the cannon.

Visible crew/equipment: During the closing scene, just as the deputy starts to walk towards the right of the screen, if you look between the two buildings, you can see the top of what appears to be a bus riding by.

Jason McCullough: How's Joe?
Jake: Oh, he figures he's going to be out of here and we're going to be dead about this time tomorrow.
Jason McCullough: Did he seem to feel any sorrow over the fact that we might all be killed?
Jake: No, it's more like he planned to dance and spit all over our graves.
Jason McCullough: Sounds like Joe.

Joe Danby: I'm gonna get you for this, Jake.
Jason McCullough: Well, you are the toughest talkin' blowhard I ever heard.

Mayor Olly Perkins: You ain't wanted for anything anywhere are you Mr. McCullough. Not that it matters, because we understand how them little things can happen.
