Only if you speak Portuguese, though. Unfortunately, I do not - Fernando Gabeira - in fairness, he is an ex-terrorist. Further, he was the kidnapping-American-ambassadors type of terrorist, rather than the flying airplanes into sky-scrapers type of terrorist. Now, he is a Brazilian politician.

I watched a movie, based on a book he wrote about his organization's activities, entitled Four Days in September. From a review on this page:

The year is 1969. Brazil is under a brutal military dictatorship. Political prisoners are being held and tortured. In order to get the junta to free some of their comrades, a group of ragtag "revolutionaries" kidnap the U.S. Ambassabor and threaten his life unless their demands are met.

Well-written and tense, the film ably demonstrates the flaws of people trying to fight fire with fire: "an eye for and eye". Alan Arkin is wonderful as the ambassador. His character gives incisive psychological sketches of his kidnappers: fervent and brooding; yearning and lost.

I'll say, it was one of the most interesting movies I've seen in quite a while. I have little else to say about it.
