Storyline

While attending a medical conference in Paris, American physician Dr. Ben McKenna, his wife, retired musical theater actress and singer Jo McKenna née Conway, and their adolescent son Hank McKenna decide to take a side trip to among other places Marrekesh, French Morocco. With a knife plunged into his back, Frenchman Louis Bernard, who the family met earlier in their bus ride into Marrakesh and who is now masquerading as an Arab, approaches Ben, cryptically whispering into Ben's ears that there will be an attempted assassination in London of a statesman, this news whispered just before Bernard dies. Ben is reluctant to provide any information of this news to the authorities because concurrently Hank is kidnapped by British couple, Edward and Lucy Drayton, who also befriended the McKennas in Marrakesh and who probably have taken Hank out of the country back to England. Whoever the unknown people the Draytons are working for have threatened to kill Hank if Ben divulges any information ... Written by Huggo

Trivia

The Marksman uses a Finnish Lahti L-35 9mm semi-automatic pistol. Actor Reggie Nalder should be a familiar face to Star Trek fans as Andorian ambassador Shras in Star Trek: Journey to Babel (1967), and to horror fans as the vampire Barlow in Salem's Lot (1979). See more »

Goofs

Prior to Dr. McKenna and Jo entering Ambrose Chapel, there is a white stain on Dr. McKenna's left shoulder, apparently from the struggle at the taxidermist. As soon as Dr. McKenna enters the chapel, the stain disappears, then reappears after they take their place in the chapel. See more »

Quotes

Dr. Ben McKenna: Yeah, me.
Jo McKenna: Mrs. Campbell's gallstones.
[both laughed]
Jo McKenna: And you know the purse I bought in Paris?
Dr. Ben McKenna: Yeah...

Crazy Credits

Partly because the rights to this film were acquired from Paramount by Universal, the Paramount VistaVision fanfare is played over the opening Universal logo. This is the way it is currently (2005) shown on television in the re-release version (1984). See more »

Revisting the man and his wife.
1 July 2018 | by cristianocrivelliSee all my reviews

I hadn't seen it since I was in college. I remembered it like a fun, absurd movie. Now in 2018 what hit me the most was the wife played by Doris Day. She is spectacular and the absurdity becomes totally real just by looking at her. James Stewart is great of course but he seems to be the foil here rather than the center that keeps us connected to that essential leap of faith. The scene in which he gives her the tranquilizers before telling her the terrible news. What Doris Day manages to do with her character is extraordinary. Brenda de Banzie is a terrific villainess and Bernard Herrmann's score another major plus. I'm sure that even my grandchildren's grandchildren will talk about The Man Who Knew Too Much and about Doris Day.
