Is Klute well-known/ well-regarded?
Klute didn't make my list
It's the first in Alan J. Pakula's paranoia themed trilogy that continues in The Parallax View and concludes in All the President's Men. All the President's Men made my list and Alan J. Pakula will be on my Top 100 directors when that comes around.
Jane Fonda has to be one of my favorite actresses from that era because of They Shoot Horses Don't They?, Klute, Coming Home, and The China Syndrome.
