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

Did You Know?


Many of the Moroccan extras had been mistakenly informed that they would only be paid if they were actually visible in the film. This led to a lot of pushing and shoving to get close to the camera until the crew explained to them that they would be paid no matter what. See more »


In the climactic scene at the Albert Hall concert, when the cymbalist stands, turns and grabs his cymbals, the timpanist beside him is playing, but is clearly not hitting the drums. Also, the timpanist is not the same person who was playing (correctly) during the title sequence. See more »


Edward Drayton: Remember, you will only have time for just one shot. If you need another, the risk is yours.
Rien: I don't take risks.

Not one of my favorite Hitchcock movies, but worth seeing.
28 March 2011 | by (United States) – See all my reviews

I'm not sure why I didn't have a more enthusiastic reaction to The Man Who Knew Too Much. Hitchcock is the director that got me interested in classic cinema, and Rear Window, Notorious, Psycho, The Birds, Rebecca, and The Lady Vanishes are all among my favorite movies. It's a globe-trotting adventure with all the tension, intrigue, assassinations, conspiracies, and suspense you could want, but there's something about it that just didn't really catch my interest until the last 30 minutes, or so. The ending is great, but the rest of the movie was just missing something, in my opinion. 

The problem certainly wasn't with the two lead actors. James Stewart gave another great performance under Hitchcock's eye (he was my favorite Hitchcock leading man), and Doris Day was charmingly determined and convincing as a confused wife  and mother, desperately searching for her son. 

The Man Who Knew Too Much certainly isn't a bad movie (is there such a thing as a bad Hitchcock movie?), and I expect that other people might have a more favorable response to it than I did. I suspect this is just one of those times when a good film just doesn't completely "click", with me, for whatever reason. I recommend it to anyone who is interested, though.
