I've seen this movie eight years ago and still think about it. This movie +simply is very, very intelligent and true. And in the same time it is very simple. It's about the racial madness of the american society. I can't think of better words to discribe the essence of this picture than those of James Baldwin, the negro american poet.
'You don't see me, I'm your black cat. You don't love me, I see that.'
'Okay. I'm your ... baby, 'till I get bigger!'
We, the viewer, see what happens every day in the american society (and of course in any other racist society): the black man is not seen, he simply is not there. And his white brother trys to kill him.
The story: The black man comes to get to know his white brother, but he, grimly with hate, seeks to kill him.
In the end, grinning and happy, the black man will tell the viewer why he accepts to play on the game and take the place of his dead white brother. And again, he could be saying the words of James Baldwin: 'And then, false lover, you will know, what love has managed here below.'
For me one of the best pictures I've ever seen. Inriching (if this word exists in english- sorry, I'm german.)
