My Fair Lady (1964)

Outside Covent Garden on a rainy evening in 1912, dishevelled cockney flower girl Eliza Doolittle (Audrey Hepburn) meets linguistic expert Henry Higgins (Rex Harrison). After delivering a musical tirade against "verbal class distinction," Higgins tells his companion Colonel Pickering (Wilfred Hyde-White) that, within six months, he could transform Eliza into a proper lady, simply by teaching her proper English. The next morning, face and hands freshly scrubbed, Eliza presents herself on Higgins' doorstep, offering to pay him to teach her to be a lady. Higgins turns his mission into a sporting proposition, making a bet with Pickering that he can accomplish his six-month miracle to turn Eliza into a lady.
