Visible crew/equipment: As the old Indian sets fire to burn his dead son, he walks towards Cain and on the left you see a fire extinguisher. (00:10:04)
The Chalice - S2-E3
Factual error: After the opening credits, Caine is walking along the beach. On the beach behind him, you can see a modern long-board surfboard lying in the sand which gets caught up in a wave.
Visible crew/equipment: During the fight on the mountain, as Caine defends himself from being struck with the shackles, you can see what looks like John Saxon leaning against a tree watching the (I presume) the stunt double and the fight. (00:45:20)
The Way of Violence Has No Mind - S2-E15
Revealing mistake: During the cabin gunfight, when Chu is out of ammo and sets the rifle down, he puts the rifle on top of 3 dozen unused rounds that are supposed to be spent rounds. (00:38:40)
Continuity mistake: Caine was once shot in the left arm, but the sling is placed to support the right arm.
Factual error: Serenity Johnson's well-worn tarot cards are from the world's most popular tarot deck created by A.E. Waite and drawn by P.C. Smith, which was first published in 1910 in England. Kung Fu takes place in the old West of the 1870s, about 40 years before the deck was published.
Visible crew/equipment: After Caine tells everyone the bird is only a creature of the earth they rush to see the boy, and just as the door is opened in the overhead shot we can see the hair of a crewmember under the crow, at the left side of the screen. Presumably it's the animal trainer. (00:28:30)
Visible crew/equipment: When the crow is on the cross Caine tells the crowd there's nothing to be afraid of in a bird, and just as he explains that it's only a creature of the earth, the shadow of the animal trainer can be seen motioning to the trained bird, then it flies off and lands on the trainer's hand. Funny to see Caine and the crowd turn and pretend to watch the bird fly in the opposite direction. (00:28:10)
Revealing mistake: When Fierro's hawk lands on the boy's arm, we can see the protective gear wrapped around the boy's arm under his sleeve. (00:06:10)
Continuity mistake: Caine leaps onto a table that has a pitcher on it, which disappears and turns into a small wooden keg that he kicks into the face of the thug fighting him.
Continuity mistake: After Caine slams the bad guy through the window of the store, the face of the stunt man playing Caine is visible and has white powder on the left side of his face. The next shot shows Caine in the store with no powder on his face.
Revealing mistake: The stunt man's face is shown as Caine grabs and throws him into the pit.
The Squawman - S2-E5
Continuity mistake: Right before the bad guy fires his rifle through the window, Caine kicks the rifle out of his hands and the bad guy jerks backwards, away from the building. The next shot the rifleman still has the rifle in both hands, and is slammed into the building by Caine.
Revealing mistake: The string controlling the black bird flying over the body of the boy in the room is visible.
Revealing mistake: David Carradine's stunt double is obvious (different face, darker hair) in the fight scene between Caine and Shelby Cross.
The Gunman - S2-E12
Continuity mistake: The close up shot shows Nedra lowering her head onto White's chest. The next shot is a long shot of her lowering her head on his chest again.
Visible crew/equipment: Modern tyre tracks from the camera truck are seen in the mud as Alethea waves goodbye to Kwai Chang Caine.
