Her views on clothes

"Joe Bradley: How much would a real interview with this dame be worth?
Mr. Hennessey: Are you referring to Her Highness?
JB: I'm not referring to Annie Oakley, Dorothy Lamour, or Madame Chiang Kai-shek.....How much?
H: What do you care? You've got about as much of a chance...
JB: I know, but if I did? How much would it be worth?
H: Oh, just a plain talk on world issues, it would probably be worth two hundred and fifty. Her views on clothes, of course, would be worth a lot more, maybe a thousand....dollars."

From Roman Holiday, in which JB is played by Gregory Peck, H by Hartley Power, both directed by William Wyler, 1953.

Well...she is a princess after all.
