Val Guest said "We shot it all out in Kitzbuhel, great cast: we had my Leo McKern again, and Michael Redgrave who was a very sick man, had terrible difficulties with his lines... Stephen [Boyd] was a wonderful person, a great giggler, a great professional, very nice guy."

The Monthly Film Bulletin wrote: "Routine spy thriller, unimaginatively scripted and directed. The entirely conventional settings include the inevitable night clubs, expensive hotels and ski slopes (where the travelling matte is much in evidence). Stephen Boyd is bland and wooden as the toy tycoon/spy; Camilla Sparv has little to do but look alluring; and Leo McKern and Michael Redgrave appear fleetingly and to little effect. The plot meanders from dull beginning to dull end with nothing of interest in between."

Leslie Halliwell said: "Dreary espionage thriller, instantly forgettable, and only watchable at odd moments while it's on."

Writing in the Los Angeles Times, critic Charles Champlin commented: "the dialogue is intermittently sophisticated, very intermittently, and the total effect is old chapeau, very old chapeau."
