When Rory Calhoun's character is described by Soo Yung who plays his Chinese godmother of sorts it reminds me of Austin Powers known as an international man of mystery. Calhoun is a good deal more serious and a good deal more deadly than Mike Myers ever was. His character reminds me a lot of Richard Widmark in Night And The City, an absolute scoundrel but who does gain the audience's sympathy somewhat.
Described by Soo Yung as a foundling left in a Hong Kong hotel when only a few weeks old, Calhoun has grown up in the criminal trade and there's also a little Pepe LeMoko in his makeup too. When we meet him he's just a passenger on a Flight To Hong Kong where a daring robbery of some diamonds on the plane is executed.
Calhoun is 'lucky' enough to be seated next to Barbara Rush who is a novelist and he intrigues her. She doesn't know that he's in on the heist, but she finds out later. As for Calhoun he dumps his long time girlfriend Dolores Donlon for Rush. In fact for Rush he makes a lot of career choices.
Besides Hong Kong the film was shot on location in Tangiers, Macao, Honolulu and San Francisco, but also in cheap black and white and it might as well have been done on a studio back lot. But the characters do keep it interesting especially Rush.
