oh ffs. Either word is acceptable Mr Pedantic.
"Movies" does sound rather an ancient term, as though it might have described what came before "talkies".
Anyway, I'm off to take the dog for his walkies.
It's not pedantry, rather a protest against the way our language is becoming permeated by so many Americanisms. I have relatives who say that something they like is "to die for." That's vomit-inducing. It's like calling biscuits, cookies and sweets, candies. That's fine in America, but citizens of the UK who do that should be dragged in to the street and executed in front of their families.
What?
