After the shootout at the end, the body count is incorrect. There are 5 gang members (2 on horseback and 3 on foot), 1 stagecoach driver and 1 riding shotgun, plus Dan and Johnny inside the stagecoach, for a total of 9 people. When the shooting starts, Dan kills one gang member on horseback and Johnny the other. One of the stage riders is wounded and the other killed. Then 2 of the gang on foot are wounded by Dan and Johnny, the 5th one gives up. After the shootout when the stage is being driven back to town by Dan, there are 2 gang members plus the stage shotgun rider alive inside the stage plus Johnny. There are 3 bodies on horses behind the stage, for a total of 8 people. Either the 5th gang member or the stage driver's body disappeared.
As the stage is headed back to Laramie at the end, the dead body on the horse on the left lifts its head.
