No, I didn't mean the moive version of Motorcycle Diaries, which is mediocre. In fact, Motorcycle Diaries is mediocre. Of all the incredible non-English literature in the world...Borges, for example, or Rilke.

Thanks for your reply. I agree with most of what you say. I don't plan to chose something overly obscure, I just wanted to know if French, German, Italian films etc. are allowed. I've found that HSC English teachers are fairly ignorant of the history of cinema, so they probably wouldn't know half the canon anyway. I might just keep a few films up my sleeve in case the question really begs for it.
I actually think markers are sympathetic to canonical works they don't know but think they should know especially if the essay they're marking is good. In my view, nearly any text will do, except perhaps really popular contemporary works, books movies that all HSC students would know, especially if you do Extension.
