The National Institute of Dramatic Art is based in Sydney, affiliated with the University of New South Wales.
It is internationally regarded. Graduates include: Cate Blanchett, Toni Collette, Judy Davis, Mel Gibson, Baz Luhrmann, Miranda Otto, Susie Porter, Richard Roxburgh, Hugo Weaving and Sam Worthington. All of these have shown signs in one form or another of the notion of folded acting.
Because this technique, at least in women, is so prevalent in Australian actresses and few other places, I suppose that the ideas can be traced to a single acting coach at NIDA. But this is only supposition, and none of the notable folded male acting comes from here.
