In my continuing attempts to resurrect public memory of Rita Tushingham's fabulous films of the sixties, here is THE KNACK from 1965 (Dir: Richard Lester). It concerns a young man's irresistible charms and whether such a skill can be passed on. Rita plays Nancy, a waif on her own in mod London who meets up with the boys.
This was Tushingham's area of expertise, playing waifs. Not classically pretty, she used her ability to play spunky yet innocent girls to great avail.
