Most movies about politics suck.
I liked ‘Dick’, a silly movie from 1999.
But my real favorites are the original “Manchurian Candidate” with Frank Sinatra and Angela Lansbury, “Dr. Strangelove” with Peter Sellers and George C. Scott, and “Primary Colors”, with John Travolta.
There are some other good ones. “All the President’s Men” is a classic.
Some other movies involve local or state politics like “Chinatown” or “The Godfather II”.
Anyway, what’s your taste?
