Here is a very nice documentory from Chris Marker (RIP), "The Owl's legacy" :

And as the contemporean inhabitants of the hellenistic's civilisation birthplace are going though so much difficulties (I'm not saying that cotemporean greeks have anything to do with Pericles and Demosthenes though) ; I think this movie speaks nicely of the former's legacy.
PS : No battle scenes inside.
