i hate to admit it and but i do not find it to be one of hitchcock best but nonetheless a riveting and climatic thriller . in a remake of hitchock 1934 movie of the same title and dr. ben mckenna ( james stewart ) the man who know too much and his wife jo mckenna ( doris day ) be holiday in morocco with their son hank ( christopher oslen ) when there be a case of mistaken identity and catch up in the web of an assassination plot . the conspirator go to extreme length to prevent them from interfere with their plot represent kidnap their beloved hank . i find it surprise that doris day and who i usually associate with rock hudson comedy and be cast in a hitchcock film . a i be watch it and i soon realize that this be more of a family film compare to hitchcock other work ( example represent psycho ) and she have sing ability need to pull off que serum serum and which she do beautifully . she be well cast a herself and james stewart have chemistry and which help make the couple believable . in comparison to the great director other work i believe this isn not a good and but it be still a exceedingly entertaining family thriller or mystery . there be also the added bonus of que serum serum and which turn out to be a smash hit for doris day . well direct and well act . a fine film .
