Decently memorable, primarily due to an outstanding sequence at the Royal Albert Hall as well as a surprisingly affecting performance by Doris Day. She's not always given that much to do, but she knocks it out of the park. The rest is a little too plodding and I'm not sure the story really makes sense, but that one setpiece was pretty fun.

Good movie, but is not the best Alfred's movies.

Que sera sera, whatever will be will be, the future's not ours to see, que sera sera

I love James Stewart in every role, but Doris Day is absolutely brilliant here.

“The Man Who Knew Too Much” is a fairly typical Hitchcock suspense thriller, although it is not one of the director’s absolute classics. While I found the beginning in Morocco very compelling, the change of location later on caused a break in the film, after which I found myself getting a little bored. Later, however, there is a really effective sequence during a concert that should have been the finale, but unfortunately it is followed by a less efficiently told section. However, “The Man Who Knew Too Much” benefits from its two leads, James Stewart and Doris Day, with Day in particular delivering a strong performance. All in all, the film is definitely worth a recommendation, even if there are much stronger Hitchcock works.
