Regarding Gary Oldman; he was also the director. There must have been a director producer argument. I did not know Speilberg was the producer.
Regarding Clinton ; there are people who believe everything Rush Limbaugh said of the man including mass murder of "witnesses" .
I wonder if Bush will ever rate a "fictional" depiction of his life on a par with 'Primary Colors'. If they do I vote for Gary Oldman to play him.
