Very good made for TV (but Oscar nominated) doc on the writer of Serpico, Midnight Cowboy and Coming Home, and who got a Sundance award named after.
It's captivating and even moving to see an artist who really did stick to his convictions at first; Salt was blacklisted, but didn't back away from feeling akin to Communist ideals, but did work on films, musicals and TV with an alias. But when he read what was really going on with Stalin and Kruschev in the mid 50s, he got disillusioned. That alone makes this story worth telling, and how he had to have a change of identity and purpose to not, well, write crap... That and learning about Taras Bulba, which Im kinda intrigued to see.
Oh, and throw him in with Gilliam and Welles as filmmakers who got obsessed with Quixote (to a fault)
