Another special movie night this month on TCM is Thursday’s “America in the ’70s,” a tribute that kicks off tonight with a roster of some of my favorite films of all time. It starts with 1976’s All the President’s Men, which is now 40 years old, but just as potent, and important, as when it was first released. Dustin Hoffman, Robert Redford star, Alan J. Pakula directs, and William Goldman wrote the teleplay, based on the Watergate book by Bob Woodward and Carl Bernstein. Brilliant, brilliant, brilliant.
