For anyone who hasn't seen Alfred Hitchcock's The Man Who Knew Too Much, this one is going to be a MAJOR SPOILER.
Now that that's out of the way, for anyone who has seen The Man Who Knew Too Much, it's quite obvious that this is the most profound moment in the entire film, the symphony scene. The 1956 film stars James Stewart as Dr. Ben McKenna and Doris Day as his wife Jo. Along with their young son Hank (Christopher Olsen), they take a trip to Morocco. A little something something goes down and Hank winds up being kidnapped and taken to London.
The McKennas stay hot on the abductors' trail and upon arriving in London, are eventually led to the Royal Albert Hall. It's there that their son's kidnappers will execute a plan to assassinate an important political figure, precisely timing the fatal gunshot with the crash of a cymbal. Unfortunately they didn't expect the McKennas to be in attendance and right when the big moment arrives, Jo lets out a scream, the killer misses his target, Ben goes after him and eventually the shooter goes over the balcony plunging to his death.
