British school children horror

 

That's from Cracked.com. I'm not sure it's an entirely irrational fear.

Here are two items from the trivia section in IMDb for Bugsy Malone (1976), the gangster musical performed entirely by tweens which was filmed in the UK:

Jodie Foster has admitted in interviews that she found many of the British cast terrifying because of the antics they would get up to.

There was a rivalry between the UK and US kids that included the UK dance girls blocking the halls in Pinewood Studios to the US actors/dancers. If they didn't give the "password", they would spray them with a fire extinguisher.

My earliest memory of British, albeit Scottish, schoolchildren was The Prime of Miss Jean Brodie. They hung a classmate over a railing and threatened to drop her to her death. I saw it in a drive-in when I was five or six and slept through the rest of it.

A review of the 1990 version of Lord of the Flies took the view that making the kids American instead of British ruined the story because the British were so civilized---American children spiraling into savagery was less dramatic because they were already halfway there. That critic may have had it backwards.
