Early in the program, when Cesar arrives at the McCain Ranch and begins whipping people- at one point Lucas grabs the whip. Mark has been standing right next to Lucas but when he grabs the whip, all of the sudden Mark is on the porch. Then the next camera angle toward Lucas, Mark is standing next to him again.
Thoughout the show there have been 9 characters in Tiffauges' entourage. Near the end, two of them are shot, but only 5 characters ride away.
The last scene where Lucas looks in on Mark is an exact repeat of the night before.
Cellophane was not even invented until 1908 and cigars weren't wrapped in it until the mid 1930's, yet Tiffauges are wrapped in it.
