Donald Clarke, Irish Times film critic, asks "Are Americans stupider than Europeans"

He asks the question in jest, of course, regarding the fact that European film names are sometimes changed when they are shown in the US.

I would add the counter-example of the Pauly Shore "classic" Encino Man which was renamed "California Man" in Europe because Europeans may not know the significance of Encino.
