Classic political intrigue, with Kirk Douglas, Fredric March, and Burt Lancaster wrapped up in a plot to overthrow the president! Heavy stuff, courtesy of Rod Serling's master writing. Unfortunately, when the going gets good -- really hitting a fever pitch on day seven -- the story goes limp and the ending is a big letdown. Still, Lancaster is unparalleled in a rare bad guy role, helped amiably by a solid supporting staff. One of Frankenheimer's best works.
