L’uomo che sapeva troppo (1956) in streaming su altadefinizione Durante una conferenza medica a Parigi, il medico americano Dr. Ben McKenna, sua moglie, l'attrice di teatro musicale e cantante in pensione Jo McKenna nata Conway, e il loro figlio adolescente Hank McKenna decidono di fare una gita, tra gli altri, a Marrekesh, nel Marocco francese. Con un coltello conficcato nella schiena, il francese Louis Bernard, che la famiglia ha incontrato in precedenza durante il viaggio in autobus per Marrakech e che ora si traveste da arabo, si avvicina a Ben, sussurrando cripticamente alle orecchie di Ben che ci sarà un tentato omicidio a Londra di uno statista, questa notizia sussurrava poco prima della morte di Bernard. Ben è riluttante a fornire qualsiasi informazione su questa notizia alle autorità perché contemporaneamente Hank viene rapito dalla coppia britannica, Edward e Lucy Drayton, che hanno anche stretto amicizia con i McKennas a Marrakech e che probabilmente hanno portato Hank fuori dal paese in Inghilterra. Chiunque sia il popolo sconosciuto per cui lavorano i Drayton ha minacciato di uccidere Hank se Ben avesse divulgato qualsiasi informazione gli fosse stata raccontata da Bernard. Con le poche informazioni che hanno a disposizione, Ben e Jo si dirigono a Londra per cercare di sventare il tentativo di omicidio e, soprattutto, trovare un Hank vivo e al sicuro. Scotland Yard è a conoscenza di alcuni pezzi del puzzle, incluso il fatto che Bernard era un agente dei servizi segreti francesi e che ci sarà un attentato a qualcuno. Loro e i McKenna dovranno lavorare insieme mentre incontrano un ostacolo diplomatico, che potrebbe essere superato con una canzone speciale di Jo Conway.
Il film ha vinto un Oscar per la migliore canzone originale per "Que Sera, Sera (Whatever Will Be, Will Be)", cantata da Doris Day. È stato presentato in anteprima al Festival di Cannes del 1956 il 29 aprile.
