Trivia / Master Ninja

• Actor Allusion: In the second episode "Out of Time Step", Charlie Collins plays Charlie Patterson. The dancing pirate film shown is Stock Footage from The Dancing Pirate, which starred Collins in the titular role.
• All-Star Cast: A surprisingly large number of well-known actors, or actors who would go on to become well-known appeared on the show. Besides Lee Van Cleef, you had appearances by the likes of Claude Akins, George Lazenby, Diana Muldaur, David McCallum, and a very young Demi Moore, among many others.
• California Doubling: More specifically, one part of California doubling for another. That's not San Francisco's Chinatown, it's Los Angeles.
• Stunt Double: A very obvious one for Lee Van Cleef.
