The Man Who Knew Too Much (1956)

Continuity mistake: Dr. McKenna is wearing a blue suit and hat during the bus ride in the beginning of the movie and then again as the family board the wagon and set out for their hotel. When the wagon arrives at their hotel and everyone gets out, McKenna's suit and hat have suddenly switched to light gray.

Jo McKenna: So, what do you do?
Louis Bernard: I buy and sell.
Jo McKenna: I see. And what do you buy and sell?
Louis Bernard: Whatever gives the most profit.

Trivia: The conductor in the symphony scene is Bernard Herrmann, who is actually playing himself. His name is seen on a poster outside the theater. Herrmann composed the music for many of Hitchcock's films, including some of the score for this one.
