the original the man who know too much brought alfred hitchcock acclaim for the first time outside of the united kingdom . of course part of the reason for the acclaim be that folk marvel how hitchcock on such a skimpy budget a compare to lavish hollywood product be able to provide so much on the screen . the original film be shoot inside a studio . for whatever reason he choose this of all his film to remake and hitchcock now with an international reputation and a big hollywood studio behind him ( paramount ) decide to see what the man who know too much would be like with a lavish budget . this be shoot on location in marrakesh and london and have two big international name for box office . this be james stewart third of four hitchcock film and his only teaming with doris day and her only hitchcock film . i do wonder why hitchcock never use doris again . at first glance she would fit the profile of blond lead lady that hitchcock favor . possibly because her wholesome screen image be at odds with the sophistication hitchcock also want in his blonde . doris do some of her best act ever in the man who know too much . her best scene be when her doctor husband james stewart give her a sedative before tell her their son have be kidnap by an english couple who befriend them in morocco . stewart and day play off each other beautifully in that scene . but doris especially a she register about four different emotion at once . day and stewart be on vacation with their son christopher olsen in morocco and they make the acquaintance of frenchman daniel gelin and the aforementioned english couple and bernard mile and brenda dabanzie . gelin be stab in the back at a market place in marrakesh and whisper some die word to stewart about an assassination to take place in albert hall in london . their child be snatch in order to insure their silence . for the only time i can think of a hit song come out of a hitchcock film . doris in fact play a noted singer who retire from the stage to be wife and mother . the song be que serum serum and i remember it well at the age of 9. you couldn not go anywhere without hear it in 1956 and it even compete with the fast rising elvis presley that year . que serum serum win the academy award for best song beat out such title a true love from high society and the title song from around the world in 80 day . it become doris day theme song for the rest of her life and still be should she ever want to come back . in fact the song be work quite nicely into the plot a doris sings it at an embassy party at the climax . instead of do it with mirror and hitchcock shoot the assassination scene at the real albert hall and like another reviewer say it not direct and it choreograph . you will be hang on your seat during that moment . this be remake well worth do .
