I don't know. It seems a bit early to be tackling this topic. Stone waited until Nixon was nearly dead (and then added the funeral epilogue to the film when he was dead) when he made Nixon.
Speaking of which, from about 1985 to 1995, Stone could do no wrong. He directed something like ten films in that period which I find to be simply amazing. But since then, he hasn't made anything that's particularly interested me (or been very good). Alexander was terrible. World Trade Center wasn't anything special. What I've seen of Any Given Sunday hasn't impressed me. And the idea of U-Turn didn't attract my attention at all.
So, this brings up the question, given the negatvie reviews of the script I've read (Even Slate, which I love, but let's face it is left leaning as hell, beat up the hell out of the script), and the fact that Stone lost all his luster as a writer director nearly 15 years ago... what do I have to look forward to in this movie?
