Woods reported some middle eastern men acting suspiciously on a flight he was on, but the FBI didn’t take it seriously. A few weeks later 9/11 happened. Later he identified a couple of the terrorists as the ones he had reported on.
I had no idea..so damn, 9/11 could have been prevented if the FBI had just listened to James Woods
He didn't notify the FBI when he saw the men. He mentioned their strange behavior (not eating, not drinking, not talking to the flight attendants, etc) to the flight attendant, and said it creeped him out, but she said they weren't doing anything to disrupt the flight, so she couldn't do anything about them. The following week was the 9/11 attacks, and when he heard that it was carried out by Middle Eastern men, he immediately called the FBI, and they came to question him the following day. I never heard that he actually identified any of the killers, but I wouldn't be surprised.
We enjoyed his TV show, "Shark", but one of my favorite movies of his is "True Believer", in which he plays a pony-tailed, tired out, liberal lawyer, a la William Kuntsler.
