There could be a yearly awards ceremony for this one... a statuette of Dick Van Dyke to the winner(s)..
Dunno if we'd call it the 'Dicks' or the 'Van Dykes'
I'll just throw in a few Worst Oirish nominations - Orson Welles in 'The Lady From Shanghai' - all that Abbey training shining through...
Kevin Spacey in 'Ordinary Decent Criminal' - where the Jasus is his accent coming from ? - 60% Cross Border 40% Mid Atlantic.
The supporting cast in it all sound badly overdubbed too - even the Irish actors.
As for the French - there's no shortage of accents over here, either, and dialects too. Haven't got a sharp enough
ear to hear violence being done to them in films - although I think it's a particularly Hollywood talent
Mind you, like English-speaking films, there is a predominance of people with bland unlocatable accents in most of
the productions. Christopher Lambert appears to be held in almost universal contempt, also, and is a
regular in the most-watched TV Satire show (Les Guignols). Somehwat similar attitude to him as you lot have to Brad/Keanu..
