Query: An example of an extinct film: the smart comedy

This movie is great in the grand sense of the word. The cast is superb, the gags are funny, and it is among the most stylish films I've ever seen. Other reasons to see it:1) Rita Tushingham stars---Tushingham is gorgeous in an unconventional way, and is known for being a gay icon---the first leading lady who preferred the company of gay men over straight.2) A young Michael Crawford in a hilarious performance3) Swinging London portrayed in a non-cliched manner.4) The film in its entirety (cast, script, setting, cinematography and wardrobe)is more "hip" and avant-garde than anything I've ever seen---and it was done forty years ago.If you are a fan of smart comedy, hip fashion and lifestyles, or just great cult films, you must have it. If you are none of these, you probably won't get. Let it be known---Lester, who is known most for A Hard Day's Night, surpassed that film tenfold in making The Knack...and How To Get It.
