One of Director John Farrow's First Assignments is a Talk-Fest with many Amusing Takes on a Chinese Warlord, "I am Fang!", Boris Karloff repeatedly Recites to Everyone. He is Ruthless and Omnipresent. But He is not without some Fairness, "Doctor good, He help China poor."
Karloff Dominates the Preceding bringing Humor, Pathos, and Charm to a Brutal Tyrant. The Film is completely Centered Around Him and it would have Failed if Not for Karloff's Commanding Performance. Everything else, the Action and the Americans are Lackluster to Say the least.
Ricardo Cortez is simply Static. It has a Twist Ending that is Sad but Satisfying considering what Came Before. Above Average for Boris Karloff Having Fun with the Villainous Anti-Hero.
