Starring: Robert Conrad, Dick Cangey, Ross Martin, Whitey Hughes
The Night of the Watery Death - S2-E9
Factual error: The coin Artemus hands West is a Morgan silver dollar. It's no coincidence that the actor's thumb covers the date on the coin in the inserted close-up. The series is set during Grant's presidential term in the early 1870s, and Morgan dollars weren't minted until 1878, after Grant had left office. (00:09:40)
The Night Dr. Loveless Died - S3-E4
Continuity mistake: In the opening scene, a cowboy sitting atop the balcony above Big Brad's Bar gets up and approaches the balcony's edge twice.
The Night of the Infernal Machine - S2-E14
Trivia: West collides with the cook and sends him sprawling face-down in a huge platter of gelatin. Before racing off again, West quips, "Sorry about that, chef!" This was a winking homage to the 60s spy comedy Get Smart and its bumbling hero Maxwell Smart's famous catch-phrase, "Sorry about that, Chief!" (00:47:30)
