When I think of 1975, let me tell you what I don't think about. Style. It's my opinion that, by and large, the mid to late 1970's, and well, much of the 1980's - well that was the time that style died. I know not everyone feels that way, but there's very little to like. So I was pleasantly surprised when I watched Three Days of the Condor.
Robert Redford looks pretty damn cool in it. Sure his blond hair is very 70's, but the outfit could easily be slightly updated today and still look great.
One thing immediately apparent when watching the movie; they just don't shoot a film this way anymore. Plenty of long shots, camera angles held for what seems to the modern attention span a long time, it's a different experience than a modern cut and jump film scene. But it manages to hold your attention. The long scenes with a static camera angle develop nicely, the scenery around the actors looms larger.
Oh yeah, and it has Max Von Sydow in it. Enough said.
