This is usually done in college in an introductory course on the western classics. Kaufman's entry in the last contest included a chorus, which led me to believe that he is familiar with Greek drama. Also, he has been to college and is even older than I am. So I think odds are good that he has enough familiarity with the plays I used.
Anyway, if you want movies, "Iphigenia at Aulis" was made into the movie Iphigenia (1977), and "Agamemnon" was made into the TV movie Agamemnon (1973).
Not to mention the classic should-have-been-#1-hit,
Iphigenia in Brooklyn.
I've seen all four of those, but in most cases long enough ago to have forgotten a bunch of the details.
However, I grew up on Mad Magazine, and learned that having seen a movie was not a prerequisite for enjoying a funny movie parody. Similarly, if people do a good enough job, I'm sure they'll win the appreciation of both the judge and the other readers.
