It's OK to look for "representative" movies and books, but I also expect my children to take interest in stories whose main characters are not of their race and sex.
From "The Souls of Black Folk" by W.E.B. Du Bois:
I sit with Shakespeare, and he winces not. Across the color line I move arm and arm with Balzac and Dumas, where smiling men and welcoming women glide in gilded halls. From out of the caves of evening that swing between the strong-limbed Earth and the tracery of stars, I summon Aristotle and Aurelius and what soul I will, and they come all graciously with no scorn nor condescension. So, wed with Truth, I dwell above the veil. Is this the life you grudge us, O knightly America? Is this the life you long to change into the dull red hideousness of Georgia? Are you so afraid lest peering from this high Pisgah, between Philistine and Amalekite, we sight the Promised Land?
Some have called this the concept of "mirror books" and "window books"... intriguing imagery, I think.
