Trailer of 1964 movie, Seven Days in May, about a military coup in the USA

http://www.imdb.com/videoplayer/vi813826329 I'm reading the book, and it is beautifully written. President Kennedy supported the making of the 1964 movie. There is a 1994 remake with Forest Whitaker playing the Marine who stumbles on the plot. It is a bit like It Can happen here, by Sinclair Lewis. I can't find the movies yet, but there are small clips on youtube. kmk 2-25-2018
