I think the theme concerning the relationship between the characters is one that has transcended the decades through film in Hollywood: The high society debutante-type, who at first, feels as if she's too good for her admirer. Many of the Tracy/Hepburn films, "Moulin Rouge", "Notting Hill", "When Harry Met Sally", "Shakespeare In Love" while not all musicals, are all based on that same theme. We root for the sweet, poor, bumbling guy who is head over heals in love ... And we are rarely disappointed, that is at least as Hollywood goes!
