sebastian be one of those movie you see once and remember for a long time . i saw it back in the seventy and and do not get to enjoy it again until i catch it on tv in the ninety . still and i remember it groovy sixty london atmosphere and it intellectually stimulating plot about codebreaking and susannah york breezy and mini skirt and somewhat flighty rebecca who be actually quite smart and bogarde coldly academic sebastian with passion seethe underneath and and jerry goldsmith right on soundtrack . like a light lecarre story and you get cold war tension and but with a post war british self deprecate viewpoint . they may not be the empire they once be and but they do have a bit of expertise in cryptography that the yank would be willing to compensate them for . donald sutherland play an nsa type at fylingdale moor who turn sebastian on ( literally ) to the late intercept from a russian satellite . he immediately impress when sebastian hear the embedded signal that carry classify data piggy back with the normal sputnik beep . mixed in with this main west versus east plot be the late sixty go go scene and with sebastian former paramour a pop singer a little past her prime and with his right hand girl a bit of a leftist sympathizer and and with his new girlfriend and rebecca and a pre hippy free spirit determine to pry him out of his oxford don shell . susannah york rebecca be fun love but have a flame hot temper that react explosively to sebastian unemotional pomposity . her true depth be shone later when she quietly remove herself to care for her baby and without the assistance of it father and sebastian and who have drop out of her life . i feel it the best role of york uneven career . what really take the movie a step above and be jerry goldsmith score . his instrumental first day at work catch just the right combination of urban excitement and spritly spirit that accompanies rebecca and a bevy of beautiful and brainy girl a they make their way in to begin their work a cryptanalyst work in sebastian high tech sweatshop . while the rest of the soundtrack be not up to his blue max or wind and the lion standard and this one tune alone put goldsmith soundtrack above most movie music . i would put this one in my list of top 100 movie for it cast and it atmosphere and it music and and it re watchability . i hope it come out on dvd soon .
