...In responding to Eastwood's Guardian interview, he said: "First of all, the man is not my father and we're not on a plantation either. He's a great director. He makes his films, I make my films ... And a comment like 'A guy like that should shut his face' - come on Clint, come on. He sounds like an angry old man right there."

Lee's comments to abcnews.com were provoked by the equally blunt interview Eastwood gave to the Guardian last week. Riled by Lee's "whites-only" mauling of his films Flags of our Fathers and Letters from Iwo Jima, Eastwood accused him of historical ignorance before growling his advice to shut up.

He also mockingly implied that Lee's views exaggerated equal opportunities by quipping about his own next big film, The Human Factor, set in post-independence South Africa: "I'm not going to make Nelson Mandela a white guy."

Now Lee has repeated his charge that black US troops, who fought in a munitions company at Iwo Jima, had not been given a second of the four hours in Eastwood's two films.

Drawing on his two degrees from universities in Atlanta and New York, he added: "I'm not making this up. I know history. I'm a student of history. And I know the history of Hollywood and its omission of the one million African-American men and women who contributed to the second world war. Not everything was John Wayne, baby."

Lee accused Eastwood of ignoring other critics who picked up on the absence of black soldiers when Flags of Our Fathers premiered.

Thomas McPhatter, a US marines sergeant who crawled up the landing beach under a hail of Japanese fire, was one of hundreds of black servicemen involved in the attack.

He said: "Of all the movies that have been made of Iwo Jima, you never see a black face. This is the last straw. I feel like I've been denied, I've been insulted, I've been mistreated. But what can you do? We still have a strong underlying force in my country of rabid racism."...
