I was going through my DVD collection the other day and ran across "Seven Days in May", a political thriller from 1964 starring Kirk Douglas, Burt Lancaster, Fredric March and Ava Gardner. It is based upon the book by Fletcher Knebel and Charles Bailey II. The screenplay was written by Rod Serling and the movie was directed by John Frankenheimer.
It is all about a plot to bring down the government of the United States by a Coup d'etat from within. Pretty graphic descriptions such as "The government of the United States is perched on the top of the Washington Monument - swaying back and forth - and may fall and break up on the pavement at any moment." Well, maybe the plot is not believable, but the cast is good and you just might be able to suspend your disbelief by the time the movie is over.
Now could we discuss the multiple attempts to impeach Donald Trump for the past three years? It isn't out as a movie yet - but there are a couple of real pageturner books out already. Start with "Witch Hunt" by Gregg Jarrett.
