Continuity mistake: As Jesse, Diamondback and Homer try to black out the windows on their car (to protect themselves from the sunlight) Homer spray paints the window next to him black. The camera angle switches to a wide shot as the car drives by. At this time, the back window (which was just blacked out) has not been spray painted yet. It is totally clean again.
Continuity mistake: When Severen kills the biker against the jukebox, the wall behind is clear of blood. A minute or so later, as Severen goes to kill the bartender, you can see the biker lying dead against the jukebox but now there is a large amount of blood sprayed on the wall. (00:47:21 - 00:48:45)
