Z (1969)

Concurrently, the military banned long hair on males; mini-skirts; Sophocles; Tolstoy; Euripedes; smashing glasses after drinking toasts; labor strikes; Aristophanes; Ionesco; Sartre; Albee; Pinter; freedom of the press; sociology; Beckett; Dostoyevsky; modern music; popular music; the new mathematics; and the letter "Z", which in ancient Greek means "He is alive!"

From the credits:

Any resemblance to actual events, to persons living or dead, is not the result of chance. It is DELIBERATE.

If you haven't seen it, you should watch Z by Costa-Gavras as soon as possible. This is one of my favorite movies of all time.
