Very little. A couple of graphs, maybe. It is, as you say, a well presented rehash of his previous interviews and writing, and I don&#x27;t think there&#x27;s anything wrong with that. The only thing that&#x27;s wrong is to call it a documentary, which it clearly isn&#x27;t -- at least, not in the ordinary sense of the term.<p>Until you pointed it out, I wasn&#x27;t aware that Chomsky didn&#x27;t write it himself. I would ordinarily find that troubling, but the script is closely based on Chomsky&#x27;s previous writing. I&#x27;m confident Chomsky would have checked it carefully and would not have agreed to participate if there was anything he was unhappy about.
