'Fraid I haven't read any of the Hedge Knight - story or graphic novel.
As for I, claudius - I'm afraid I've never seen the BBC adaption, which I figure is the one you mean? I'd love to see them, though. A problem I have with the books is that Claudius is rather romanticised from the historical depiction - the character of the book just seems too removed from the figure in Suetonious.
As for the Greeks - my interest lies primary with Rome, but Greece during the 5th-4th centuries BC is the period I've read most around. I figure you've read Thucydides, Peloponnesian War? Of all the original ancient histories I've read, his was probably my favourite - the way he brings the entire conflict to life - from the drama to the ridiculous - makes for great reading.
As for Macedon - almost surprised by that - especially when remembering Alexander's infamous tribute to the Greeks, when he dedicated his conquests to the Greeks "except the Laecedomians". Quite a snub that.
As for Themopylae - heh, I want to see more emphasis on the allies. Seems too many people have this strange idea of 400 spartans standing alone at the pass - guess the old epic film helps with that. In the current re-making I really hope we see something more of the 15,000 Thespians and other allies who fought in that battle ,too.
