Unfortunately, it appears with every passing day that the great American paranoid political thrillers of the 60's and 70's, with its strongest work bookended by 'The Manchurian Candidate' (eerily foreseeing the JFK assassination) and 'All the President's Men' (placing a coda of closure on the Watergate scandal), simply haven't aged a day, and are as timely as ever in conceptualizing the palpable fear that ordinary citizens have in those in control of their destinies, namely the police and government of their communities. It's the American ideal that any person born, regardless of circumstances, is in control of their destiny, and that with hard work, guile and determination, can make something of himself. Whether that was ever the case is questionable, but it seems more than ever that the people in power are in control of way more than we could ever suppose, or would ever want to know.
This was a nice smaller-scale film that, incredulously, Coppola was able to dish up in a run that is one of the finest a director would ever have, up there with Hitchcock's in the late 50's-early 60's, and Melville a decade later. It's definitely excellent work by Hackman (along with his Popeye Doyle in the pair of great 'French Connection' movies), and is up there with the greatest dissertations ever about the double-edged sword of surveillance, namely De Palma's 'Blow Out' and Antonioni's 'Blow-Up'.
As a human being, I only wish this film wasn't as important as it is.
Gene Hackman is superb here as "Harry" - a super-efficient surveillance expert who discovers in the line of duty that a couple he is monitoring might well be about to be murdered. It becomes clear that the couple - Cindy Williams & Frederic Forrest are having an affair but that is just the tip of the conspiratorial iceberg in this tautly scripted/directed effort from Francis Ford Coppola. It's a slow burn, at times it certainly does drag, but the subtleties with which the cat and mouse swap places, alongside some great supporting roles from John Cazale and Harrison Ford make it quite an enthralling watch - and certainly one of Hackman's best, most emotionally charged, performances.
