In honor of this week’s public release of the Pentagon Papers, it’s heroic journalism week here. We begin with this paranoid classic. The relentlessly louche Warren Beatty is pretty improbable as a crusading journalist, but the pure weirdness of the story is ample compensation. As usual in Pakula, banal and efficient modern spaces — parking garages, convention halls, office buildings, airports — intensify the horror and dread. This was made at a time when Americans were just getting used to living with the idea our leaders lie to us as a matter of course, but were still capable of being scandalized. Pakula captures the zeitgeist with verve.
