Well thanks for all the suggestions folks, I'm sure I will buy some more eventually, and I'm not averse to 'heavy,' just not for this particular occasion.
Happily amazon are having a world film sale just now so I got:
City of Lost Children
Diner des Cons
He Loves Me, He Loves Me Not
Un long dimanche de fiançailles, from Amazon uk, all for £18
And as it was hideously expensive, (and now it seems, out of stock) at .co.uk,
Bienvenue chez les Ch'tis, from Amazon.fr
- I think they all would have been cheaper from Amazon France had there not been the world film sale on.
so hopefully there will be at least something there we will all watch....
