I was only sorry that they did not mention his turn as Detective MacDuff in the Macbeth update "Scotland, PA", which was so fucking entertaining. Of note, he is the LEAST creepy character in that film.
Good article. Like Claudia, I think there's a film missing from the article: The Dogs of War, which is probably the best film about mercenaries out there, and it's a heck of a lot better than the Forsyth novel on which its based. The ending is vintage Walken.
