Germany's answer to James Bond is not that much bad :handsome Horst Buchholz has plenty of go and of humor ; his acrobatics (hats off to the stuntman!) are impressive and makes you giddy .
Actually the secret agent is statuesque Sylva Koscina , but ,as the macho hero says to her while he locks her in the cupboard "it's a man job" ,and her role is boiled down to a decorative one ; French Perette Pradier ,herself a spy thriller habituée ("Furia à Bahia pour OSS 117""le judoka agent secret" "house of cards" )provides the obligatory second female "Bond" girl .....
There are several nods to OO7 : Istambul will remind you of "from Russia with love" ;the scrapyard of "Goldfinger" ;and the fight in the pool under water is pure "thunderball" ,though the latter movie was not yet released .
The cinematography is fine, the screenplay knows only one tempo :accelerated,and there's never a dull moment.
Buchholz and Koscina would team up again the following year in Yves Allégret's "Johnny Banco " but this once great director was only the ghost of himself and it was a fiasco.
