Good political thrillers from the 1970s? or other good 70s movies?

In reviews for the movie Michael Clayton, reviewers keep saying things like “harkens back to the political thrillers of the 1970s.” Since I was born in 79, I missed out on most of the 70s screen adventures. I enjoyed Michael Clayton, and I also loved the only other political 1970s movie I’ve seen…“All the Presidents Men”. What other 1970s movies would fall into this genre? The Sting was also really good…not quite a political thriller but just a good movie from the 70s.
