Mumblecore

I read an article in the NY Sunday Times about Mumblecore. This is a new film movement (I guess only in America at the moment) that relies on naturalistic, low-budget production and often improvised dialogue. It's apparently a defining genre for today's 20-somethings. So will Hollywood or Madison Ave find it first? Will it translate to the UK? And, maybe interestingly, why on earth would a traditional ad agency be any better at making mumblecore ads than say a 20-something video-literate blogger? Perhaps this is another example of how traditional classifications and definitions of agency specialisation are going to erode. And another question mark over how agencies resource.
