Quite so — and the point of my OP was that the film distributors who translated 'Les 400 Coups' as 'The 400 Blows' were performing an act equivalent to saying that something "prends le gateau". It should have been called something like "Kicking Up A Storm", or some such, to render the original title idiomatically: but "The 400 Blows" just has no meaning, and makes no sort of idiomatic impact, in English.
