had a very free-flowing fantasy life, which he drew on." Perkins came up with the idea of filming a sex scene with both characters wearing sunglasses in bed. Susan Clark said, "He was very alive and always able to find some quirk in the character. But the man himself was very private, very mischievous. He would throw a line one way in rehearsal — then do a different inflection to see if you were really listening during the take." Reception Spies and Sleuths called the movie "a muddle film that cannot untie its tangled skein of a plot, although a Perkins performance is always worth watching." Starburst wrote, "This convoluted thriller is not without its merits (not least some clever dialogue and well observed performances by, among others, Anthony Perkins.) The trouble is, Bloomfield has not learned from the brilliant Point Blank that an oblique, difficult narrative can be gripping (even if one is only gradually aware of what's going on) — here the effect is wearingly muddlesome."
