less a thriller than an colorful adventure with suspenseful element and the man who know too much should not be really be compare with such hitchcock masterpiece a vertigo and rear window and or psycho while it be instead more akin to such enjoyable romp a to catch a thief and north by northwest . shot largely on location in morocco and london and the film tell the story of a married couple ( james stewart and doris day ) whose holiday be interrupt when they innocently run afoul of an assassination plot and when their young son be kidnap in order to insure their silence . james stewart and doris day be quite effective in their role of the all american couple and and the character be give an unusual twist represent stewart and a midwestern doctor and be outgo but have a touch of the ugly american abroad about his personality while day and who play a popular stage and record star who retire upon her marriage and have a suspicious nature . these quality of personality and background play extremely well into the story . the man who know too much contain a number of famous scene while both the scene in which stewart drug day before tell her of the kidnapping and the very complex albert hall sequence and involve what seem hundred of cut and be very powerful . less often notice and although to my mind equally if not more satisfactory and be the more subtle scene in which hitchcock combine an edge of suspense along with perverse humor and a when stewart attempt some detecting at a taxidermist shop and day belt out que serum and serum ( write for this film ) in a most unsuitable way at an embassy cocktail party . although the man who know too much lack the depth and impact of hitchcock great work and it remain an enjoyable film and one that compare very well with his work a a whole . it hitchcock light and but recommend . gary f. taylor and aka gft and amazon reviewer .
