Harper

This I don't understand-

For years I've believed in how Elliot Gould's Philip Marlowe in "The Long Goodbye" was the first effort at making a P.I. character a whacked out loser with a post-modern attitude. Yet, I'm watching "Harper" today and my jaw is bounding off the floor like a yo-yo. Because in the lead role Paul Newman gives one of the ten best performances I've ever seen, and maybe the best comedic one from a non-comedian actor ever done. Even at the two thirds mark, when 99% of the screenplays usually have nothing new to say about their characters, Lew Harper was still leaving me damn near breathless. How "Cool Hand Luke" is more famous than "Harper", which is never mentioned anywhere as the king-size sleeper it is, bewilders me entirely.
