Much is said concerning the merits of re-imagining the Philip Marlowe character in the swinging sixties, bringing to it a pop culture emphasis that seems eons away from Humphrey Bogart's turn, but there's three good reasons to consider this Marlowe adaptation.
First-rate cast stars the always affable James Garner in the title character. He's a modest Marlowe, not arrogant, assuming nor especially gifted at his trade, he toils and the rewards follow (albeit with some distress involved). Lovely Gayle Hunnicutt plays the femme fatale along with little sister Sharon Farrell, while Rita Moreno trumps them both with a critical role as a stripper of more than passing resemblance to Hunnicutt.
Then there's the surprise packet, namely, Bruce Lee with just a couple of scenes, one of which involving him demolishing Garner's office like it was made of balsa wood. A perfectly timed scissor kick shatters the overhead light shade (a good foot above his own head), before he dons his sunglasses, turns on his heel and casually walks out the door he's just kicked in half. It's a stern warning to Garner to lay off, but equally hilarious in its approach of which both Lee and Garner seem aware. If you take nothing from the film, you'll always remember that scene.
And finally, if you're familiar with them, the theme tune "Little Sister" is a catchy jazz-pop song by Orpheus, the band who had four albums of jazz-psychedelic pop in the mould of what would later become the signature of Lighthouse, Chicago and others of the ilk. Great adaptation, a real time capsule of the era and well worth a look.
