You either have it or you don't. The knack, that is, of seduction! From the director of the Beatles' movies A Hard Day's Night and Help! comes this "inventive and hilarious" (Time) romp through love and sex in 1960's London. Featuring Richard Lester's frenetic filmmaking style - careening from slapstick to serious to avant-garde - this "genuinely dazzling" (Los Angeles Times) film is a mod masterpiece!Cool and sophisticated Tolen (Ray Brooks) has a monopoly on womanizing - with a long line of conquests to prove it - while the na ve and awkward Colin (Michael Crawford) desperately wants a piece of it. But when Colin falls for an innocent country girl (Rita Tushingham), it's not long before the self-assured Tolen moves in for the kill. Is all fair in love and war, or can Colin get the knack and beat Tolen at his own game?
