Sadly, actor Theo Marcuse (Abdul Hassan) did not live to see this episode broadcast. The 47-year-old actor died in a car accident on November 29, 1967.
By 1850, the southern U.S. was the world's largest cotton source, although India and Egypt had strong cotton production. When the Civil War started, England and France invested heavily in Egyptian cotton fields. Those investments failed when U.S. cotton production quickly rebounded after the war, and the Egyptian economy subsequently collapsed.
Even though Dawn Wells and Sandra Wells appear in this episode they are not related. Sandra Wells was born as Sandra Gasaway.
Mustachioed stuntman Whitey Hughes appears as three different characters within nine minutes. He is the poncho-wearing bandito who meets the stage West is driving, the scimitar-wielding guard at Hassan's hacienda, and when escaping on a zip-line, West drops onto a horse being ridden by Hughes.
The scene where James West climbs up the rocks, then kicks the sentinel off the cliff, was previously used in Season 3 Episode 5, The Night of Jack O'Diamonds.
