The Knack... and How to Get It (1965)

Cool, sophisticated Tolen (Ray Brooks) has a monopoly on womanizing--with a long line of conquests to prove it--while naïve, 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 The Knack and beat Tolen at his own game?
