From the Elder Statesman:

Horns and Halos. (B) A documentary about one man's attempt to publish an unauthorized biography of George W. Bush during the 2000 presidential campaign. The book's title was "Fortunate Son," and it portrayed Bush as a lightweight backed by a powerful political family and economic interests. The foci of the documentary are the author, an ex-con who had turned his life around, and his promoter/publisher, a sincere believer in his message who takes on the project after the author's major publisher backs out, allegedly under pressure from "the interests." But the documentarian does not avoid the shaky aspects of the author's story, which makes it a pretty compelling film.
