BBC has made some of the best documentaries on art - music, dance, painting etc. 'How art made the world' is probably the most prominent among them. It's a multi-disciplinary composition that was broadcast as a five part series. The amount of research that has gone into making the kind of correlations that they make is stunning. It's available for download in torrent, and I strongly recommend that you do.
However, there is one segment - consisting a concrete analogical fact - that I have found extremely useful in discussing matters concerning racism, 'unreal body images' etc (to differentiate between socially constructed "instincts" and natural instincts) for quite sometime. I should have uploaded it much earlier.
That 'fact' might also explain the Tamil audience's obsession with 'plump' heroines like Kushbu and Jyothika. I think we, well, many of us, are still in close contact with our primaeval instincts, after all.
