This French drama has aged quite well. I remember watching it in the wake of the Bond craze during the early 1960s and it did not fare very well with me, as I was comparing it to Sean Connery's adventures, surrounded by international locations, exotic women and decors. Dubbed in English, "Banco a Bangkok" had little chance against the 1964 entry of the Bond franchise, "Goldfinger", which is regarded as one of the best in the series.
But seeing it again in French, with no reference in mind, "Banco a Bangkok" is an action drama in which finesse, sexual tension and exoticism merge in a gentle way. Car and boat chases, killings or martial arts fights are not lacking, but violence and sadism are handled sparingly, while the usual story of world dominance is told.
The action takes place in Thailand, among colorful characters: an American colonel, Hubert Barton or OSS 117, a code name never used in the plot; mister and miss Sinn, two Caucasian brothers who are supposed to be Thais; Eva, a blonde secretary out of a Bond vehicle, many Thais as assistants of heroes and villains, a free-lance ex-Nazi hustler called Karloff (only in the final roll-up), and a sect of fascist survivalists called The Chosen People.
For Kerwin Mathews (as Barton) this was one of the first movies he made in the last phase of his career, that would evolve into grade-B movies in Europe and the USA. Here he is aging well, with gray hair highlighting his boyish charm, and he seems to be having a good time in a quality product. Robert Hossein plays his usually wicked, handsome villain, while Pier Angeli is the antithesis of the scantily clad, stereotyped Bond girl, properly dressed in Thai fashion.
Sensuality is a game all over (I even felt a homoerotic undercurrent), the tone is light, the humor is kept in check, and the use of Thailand locations is effectively handled by co-director Jacques Besnard. Order Thai food and beer, and enjoy.
