The '70s were the Golden Era for political thrillers (All the President's Men, Parallax View, The Conversation, Executive Action, Twilight's Last Gleaming, The China Syndrome...).
There are a couple of upcoming movies in that genre to watch for ..
First a movie about Ed Snowden ..
Snowden starring Joseph Gordon-Levitt, Shailene Woodley and Timothy Olyphant.
Also one about Dan Rather and the kerfuffle surrounding the 60 Minutes piece on Dubya (
Truth). It just so happens to star the star of 3 Days of the Condor (and All the President's Men .. Robert Redford) as Dan Rather.

Should be interesting.
