Life imitating art

Not that the art in question is within my range, but people were going into bookshops trying to find a book they'd seen in the movie of Sex and the City. The book didn't exist. Its title? Love Letters of Great Men. The publishers Macmillan are now producing a book of the same title, containing, well, love letters of great men. I take no credit for the idea. But when you see whose idea it was, you will understand my interest in it.
