ADVISE AND CONSENT and THE BEST MAN are my favorite political modern films. The other ones ( SEVEN DAYS IN MAY, DR. STRANGELOVE and the later THE CANDIDATE ) aren't nearly as good; though Dr. STRANBGELOVE is really just a black comedy and shouldn't count in this list. And the much later ones are all UTTER GARBAGE!
The much earlier movies are either just silly fluff or Commie propaganda ( ANGEL ON MY SHOULDER ), and not to be taken seriously.
I”m not a huge fan of The Best Man although my husband is. I love Dr. Strangelove because it is just very silly as well as hilarious - what a performance from Peter Sellers! My favorite is Advise and Consent with my beloved Walter Pidgeon and Charles Laughton. With a very good performance from NYC actor, George Grizzard!
