This was director Andre Hunebelle's third crack at OSS 117, the hero of Jean Bruce's novels, and we consider it probably his best effort. OSS 117 Mission For a Killer has a lot going for it. Among them is Frederick Stafford. He's just right as the smart and tough Hubert Bonnisseur de la Bath. He has an easy air of capability about him and we were surprised to learn that this was his first film credit. Stafford, who died in a plane crash in 1979, played the same role in OSS 117 From Tokyo With Love and he made one other spy flick in the sixties; Agent 505 - Death Trap Beirut.
After four political assassinations occur inside a month, all perpetrated by drug-induced innocents, Stafford is sent to Rio to track down the source of the narcotic. Since it's Rio, we are treated to the prerequisite Carnival footage but it doesn't take up too much time. The Latin-inflected score by Michel Magne is just fine and in fact, blends well with the Rio and Bahia area locations. The film has plenty of action, good fights and intentional humor. Overall this is a superior example of the genre and well worth seeking out.
