Too many people only thought of Capote as this odd, little man who showed up on talk shows during the '70s. This movie helps people remember that he was a very serious artist and writer, not just some self-absorbed celebrity.
The movie shows how much of his life Capote put into 'In Cold Blood' and the toll it took on him. He made it a literary phenomenon and it was a hard act to follow. No matter what he did, he could never top it.
