When the stuntman playing Sheriff Cord is "shot" and jumps out of the tower at the end, it's clear that he's making a carefully controlled jump and pushing himself off with his arms out, rather than clutching at his stomach and falling over the edge.
Disguises: reporter Ned Buntline
Artie has photographs of three of his former disguises. The problem is, they are all photos of him "in the field," when he was in court, at a bar, and winking at a sergeant, respectively. There were no photographers present at any of those times in the previous episodes... so where did the photos come from?
Gadgets: sleeve derringer and line on a belt reel attached to pulley, windup lockpick, trick pipe with knockout gas, boot knife
Disguises: elderly fisherman
Artie rather casually and uncharacteristically lets a man drown to death in the third act, gassing him unconscious then letting him fall into the water.
Artie reviews his list of disguises from previous episodes in a rare moment of inter-episode continuity: Aaron Addison, businessman, age 68 (from "TNOT Legion of Death"); Paulo Martinez, Portuguese fisherman, age 33 (from "TNOT Samurai"); Lt. Jonathan Greeley, 7th Cavalry (from "TNOT Arrow"); Jake the Piano Player in Deadwood (from "TNOT Cut-throats").
Gadgets: a flare bullet, wind-up lockpick, thermite charges, sleeve derringer with rope and dart
Disguises: Lt. Greeley, a hungry frontiersman, Strong Bear
Trivia: The letter of resignation President Grant reads aloud from General Baldwin dates this story as concluding on April 6, 1874.
Artie pours grant a glass of whiskey that's only a third full. When Grant picks it up in the next shot, it's over half full.
Aimee claims that Horage Greeley is the editor of the New York Herald. However, he was the editor of the New York Tribune.
Before the first commercial break, Aimee is surrounded by six Indians. After the break, two of them have disappeared.
Although Oconee tells Jim to go to the cave at 8 p.m., it's broad daylight throughout the entire scene from when Jim rides up the mine until he goes to the lake.
Disguises: actor Johnathan Ashley Kingston, bald waiter
Although Britt Nilsson's character is listed as Joan in the credits (and the closed-captioning on the DVD) Artie (as Jonathan) introduces her to West as "Joanne."
At the end, Jim and Artie are apparently playing real poker for real stakes, judging by Artie's concern about losing. And yet when he hits the trick table top, it flips over revealing that the chips are all glued to the table. It's not clear why they would be playing poker while sitting next to a table with poker chips glued to it.
Gadgets: wind-up explosive, smoke grenade, humidor rigged to shoot out fake snakes
Disguise: Count Draja
Jim says he and Draja are going to hole up at the abandoned shack come nightfall. In the following scene, the shots of the shack from the outside are in broad daylight, while the shots inside have windows that look out on a dark night.
